>gnl|CDD|200467 cd11328, AmyAc_maltase, Alpha amylase catalytic domain found in
maltase (also known as alpha glucosidase) and related
proteins. Maltase (EC 3.2.1.20) hydrolyzes the
terminal, non-reducing (1->4)-linked alpha-D-glucose
residues in maltose, releasing alpha-D-glucose. In most
cases, maltase is equivalent to alpha-glucosidase, but
the term "maltase" emphasizes the disaccharide nature of
the substrate from which glucose is cleaved, and the
term "alpha-glucosidase" emphasizes the bond, whether
the substrate is a disaccharide or polysaccharide. The
Alpha-amylase family comprises the largest family of
glycoside hydrolases (GH), with the majority of enzymes
acting on starch, glycogen, and related oligo- and
polysaccharides. These proteins catalyze the
transformation of alpha-1,4 and alpha-1,6 glucosidic
linkages with retention of the anomeric center. The
protein is described as having 3 domains: A, B, C. A is
a (beta/alpha) 8-barrel; B is a loop between the beta 3
strand and alpha 3 helix of A; C is the C-terminal
extension characterized by a Greek key. The majority of
the enzymes have an active site cleft found between
domains A and B where a triad of catalytic residues
(Asp, Glu and Asp) performs catalysis. Other members of
this family have lost the catalytic activity as in the
case of the human 4F2hc, or only have 2 residues that
serve as the catalytic nucleophile and the acid/base,
such as Thermus A4 beta-galactosidase with 2 Glu
residues (GH42) and human alpha-galactosidase with 2 Asp
residues (GH31). The family members are quite extensive
and include: alpha amylase, maltosyltransferase,
cyclodextrin glycotransferase, maltogenic amylase,
neopullulanase, isoamylase, 1,4-alpha-D-glucan
maltotetrahydrolase, 4-alpha-glucotransferase,
oligo-1,6-glucosidase, amylosucrase, sucrose
phosphorylase, and amylomaltase.

>gnl|CDD|200494 cd11359, AmyAc_SLC3A1, Alpha amylase catalytic domain found in
Solute Carrier family 3 member 1 proteins. SLC3A1, also
called Neutral and basic amino acid transport protein
rBAT or NBAT, plays a role in amino acid and cystine
absorption. Mutations in the gene encoding SLC3A1 causes
cystinuria, an autosomal recessive disorder

>gnl|CDD|200472 cd11333, AmyAc_SI_OligoGlu_DGase, Alpha amylase catalytic domain
found in Sucrose isomerases, oligo-1,6-glucosidase (also
called isomaltase; sucrase-isomaltase; alpha-limit
dextrinase), dextran glucosidase (also called glucan
1,6-alpha-glucosidase), and related proteins. The
sucrose isomerases (SIs) Isomaltulose synthase (EC
5.4.99.11) and Trehalose synthase (EC 5.4.99.16)
catalyze the isomerization of sucrose and maltose to
produce isomaltulose and trehalulose, respectively.
Oligo-1,6-glucosidase (EC 3.2.1.10) hydrolyzes the
alpha-1,6-glucosidic linkage of
isomaltooligosaccharides, pannose, and dextran. Unlike
alpha-1,4-glucosidases (EC 3.2.1.20), it fails to
hydrolyze the alpha-1,4-glucosidic bonds of
maltosaccharides. Dextran glucosidase (DGase, EC
3.2.1.70) hydrolyzes alpha-1,6-glucosidic linkages at
the non-reducing end of panose, isomaltooligosaccharides
and dextran to produce alpha-glucose.The common reaction
chemistry of the alpha-amylase family enzymes is based
on a two-step acid catalytic mechanism that requires two
critical carboxylates: one acting as a general acid/base
(Glu) and the other as a nucleophile (Asp). Both
hydrolysis and transglycosylation proceed via the
nucleophilic substitution reaction between the anomeric
carbon, C1 and a nucleophile. Both enzymes contain the
three catalytic residues (Asp, Glu and Asp) common to
the alpha-amylase family as well as two histidine
residues which are predicted to be critical to binding
the glucose residue adjacent to the scissile bond in the
substrates. The Alpha-amylase family comprises the
largest family of glycoside hydrolases (GH), with the
majority of enzymes acting on starch, glycogen, and
related oligo- and polysaccharides. These proteins

oligo-1,6-glucosidase (also called isomaltase;
sucrase-isomaltase; alpha-limit dextrinase) and related
proteins. Oligo-1,6-glucosidase (EC 3.2.1.10)
hydrolyzes the alpha-1,6-glucosidic linkage of
isomalto-oligosaccharides, pannose, and dextran. Unlike
alpha-1,4-glucosidases (EC 3.2.1.20), it fails to
hydrolyze the alpha-1,4-glucosidic bonds of
maltosaccharides. The Alpha-amylase family comprises the
largest family of glycoside hydrolases (GH), with the
majority of enzymes acting on starch, glycogen, and
related oligo- and polysaccharides. These proteins
catalyze the transformation of alpha-1,4 and alpha-1,6
glucosidic linkages with retention of the anomeric
center. The protein is described as having 3 domains: A,
B, C. A is a (beta/alpha) 8-barrel; B is a loop between
the beta 3 strand and alpha 3 helix of A; C is the
C-terminal extension characterized by a Greek key. The
majority of the enzymes have an active site cleft found
between domains A and B where a triad of catalytic
residues (Asp, Glu and Asp) performs catalysis. Other
members of this family have lost the catalytic activity
as in the case of the human 4F2hc, or only have 2
residues that serve as the catalytic nucleophile and the
acid/base, such as Thermus A4 beta-galactosidase with 2
Glu residues (GH42) and human alpha-galactosidase with 2
Asp residues (GH31). The family members are quite
extensive and include: alpha amylase,
maltosyltransferase, cyclodextrin glycotransferase,
maltogenic amylase, neopullulanase, isoamylase,
1,4-alpha-D-glucan maltotetrahydrolase,
4-alpha-glucotransferase, oligo-1,6-glucosidase,
amylosucrase, sucrose phosphorylase, and amylomaltase.

>gnl|CDD|233874 TIGR02456, treS_nterm, trehalose synthase. Trehalose synthase
interconverts maltose and alpha, alpha-trehalose by
transglucosylation. This is one of at least three
mechanisms for biosynthesis of trehalose, an important
and widespread compatible solute. However, it is not
driven by phosphate activation of sugars and its
physiological role may tend toward trehalose
degradation. This view is accentuated by numerous
examples of fusion to a probable maltokinase domain. The
sequence region described by this model is found both as
the whole of a trehalose synthase and as the N-terminal
region of a larger fusion protein that includes
trehalose synthase activity. Several of these fused
trehalose synthases have a domain homologous to proteins
with maltokinase activity from Actinoplanes
missouriensis and Streptomyces coelicolor
(PMID:15378530) [Energy metabolism, Biosynthesis and
degradation of polysaccharides].

Cyclomaltodextrinase (CDase; EC3.2.1.54), neopullulanase
(NPase; EC 3.2.1.135), and maltogenic amylase (MA; EC
3.2.1.133) catalyze the hydrolysis of alpha-(1,4)
glycosidic linkages on a number of substrates including
cyclomaltodextrins (CDs), pullulan, and starch. These
enzymes hydrolyze CDs and starch to maltose and pullulan
to panose by cleavage of alpha-1,4 glycosidic bonds
whereas alpha-amylases essentially lack activity on CDs
and pullulan. They also catalyze transglycosylation of
oligosaccharides to the C3-, C4- or C6-hydroxyl groups
of various acceptor sugar molecules. Since these
proteins are nearly indistinguishable from each other,
they are referred to as cyclomaltodextrinases (CMDs).

found in maltogenic amylases, cyclodextrin
glycosyltransferase, and related proteins. Enzymes such
as amylases, cyclomaltodextrinase (CDase), and
cyclodextrin glycosyltransferase (CGTase) degrade starch
to smaller oligosaccharides by hydrolyzing the
alpha-D-(1,4) linkages between glucose residues. In the
case of CGTases, an additional cyclization reaction is
catalyzed yielding mixtures of cyclic oligosaccharides
which are referred to as alpha-, beta-, or
gamma-cyclodextrins (CDs), consisting of six, seven, or
eight glucose residues, respectively. CGTases are
characterized depending on the major product of the
cyclization reaction. Besides having similar catalytic
site residues, amylases and CGTases contain carbohydrate
binding domains that are distant from the active site
and are implicated in attaching the enzyme to raw starch
granules and in guiding the amylose chain into the
active site. The maltogenic alpha-amylase from Bacillus
is a five-domain structure, unlike most alpha-amylases,
but similar to that of cyclodextrin glycosyltransferase.
In addition to the A, B, and C domains, they have a
domain D and a starch-binding domain E. Maltogenic
amylase is an endo-acting amylase that has activity on
cyclodextrins, terminally modified linear maltodextrins,

Cyclomaltodextrinase (CDase; EC3.2.1.54),
neopullulanase (NPase; EC 3.2.1.135), and maltogenic
amylase (MA; EC 3.2.1.133) catalyze the hydrolysis of
alpha-(1,4) glycosidic linkages on a number of
substrates including cyclomaltodextrins (CDs), pullulan,
and starch. These enzymes hydrolyze CDs and starch to
maltose and pullulan to panose by cleavage of alpha-1,4
glycosidic bonds whereas alpha-amylases essentially lack
activity on CDs and pullulan. They also catalyze
transglycosylation of oligosaccharides to the C3-, C4-
or C6-hydroxyl groups of various acceptor sugar
molecules. Since these proteins are nearly
indistinguishable from each other, they are referred to
as cyclomaltodextrinases (CMDs). This group of CMDs is
bacterial. The Alpha-amylase family comprises the
largest family of glycoside hydrolases (GH), with the
majority of enzymes acting on starch, glycogen, and
related oligo- and polysaccharides. These proteins
catalyze the transformation of alpha-1,4 and alpha-1,6
glucosidic linkages with retention of the anomeric
center. The protein is described as having 3 domains: A,
B, C. A is a (beta/alpha) 8-barrel; B is a loop between
the beta 3 strand and alpha 3 helix of A; C is the
C-terminal extension characterized by a Greek key. The
majority of the enzymes have an active site cleft found
between domains A and B where a triad of catalytic
residues (Asp, Glu and Asp) performs catalysis. Other
members of this family have lost the catalytic activity
as in the case of the human 4F2hc, or only have 2

hydrolases (GH), with the majority of enzymes acting on
starch, glycogen, and related oligo- and
polysaccharides. These proteins catalyze the
transformation of alpha-1,4 and alpha-1,6 glucosidic
linkages with retention of the anomeric center. The
protein is described as having 3 domains: A, B, C. A is
a (beta/alpha) 8-barrel; B is a loop between the beta 3
strand and alpha 3 helix of A; C is the C-terminal
extension characterized by a Greek key. The majority of
the enzymes have an active site cleft found between
domains A and B where a triad of catalytic residues
(Asp, Glu and Asp) performs catalysis. Other members of
this family have lost the catalytic activity as in the
case of the human 4F2hc, or only have 2 residues that
serve as the catalytic nucleophile and the acid/base,
such as Thermus A4 beta-galactosidase with 2 Glu
residues (GH42) and human alpha-galactosidase with 2 Asp
residues (GH31). The family members are quite extensive
and include: alpha amylase, maltosyltransferase,
cyclodextrin glycotransferase, maltogenic amylase,
neopullulanase, isoamylase, 1,4-alpha-D-glucan
maltotetrahydrolase, 4-alpha-glucotransferase,
oligo-1,6-glucosidase, amylosucrase, sucrose

FCB2 (AKA L-lactate:cytochrome c oxidoreductase) is a
respiratory enzyme located in the intermembrane space
of fungal mitochondria which catalyzes the oxidation of
L-lactate to pyruvate. FCB2 also participates in a
short electron-transport chain involving cytochrome c
and cytochrome oxidase which ultimately directs the
reducing equivalents gained from L-lactate oxidation to
oxygen, yielding one molecule of ATP for every
L-lactate molecule consumed. FCB2 is composed of 2
domains: a C-terminal flavin-binding domain, which
includes the active site for lacate oxidation, and an
N-terminal b2-cytochrome domain, required for efficient
cytochrome c reduction. FCB2 is a homotetramer and
contains two noncovalently bound cofactors, FMN and
heme per subunit.

the conversion of GTP into dihydroneopterin
triphosphate. The enzyme product is the precursor of
tetrahydrofolate in eubacteria, fungi, and plants and of
the folate analogs in methanogenic bacteria. In
vertebrates and insects it is the biosynthtic precursor
of tetrahydrobiopterin (BH4) which is involved in the
formation of catacholamines, nitric oxide, and the
stimulation of T lymphocytes. The biosynthetic reaction
of BH4 is controlled by a regulatory protein GFRP which
mediates feedback inhibition of GTP-CH-I by BH4. This
inhibition is reversed by phenylalanine. The decameric
GTP-CH-I forms a complex with two pentameric GFRP in the
presence of phenylalanine or a combination of GTP and
BH4, respectively.
