>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.

rBAT or NBAT, plays a role in amino acid and cystine
absorption. Mutations in the gene encoding SLC3A1 causes

subunit (Formate-Dh-Na) is a major component of nitrate
respiration in bacteria such as in the E. coli formate
dehydrogenase N (Fdh-N). Fdh-N is a membrane protein
that is a complex of three different subunits and is the
major electron donor to the nitrate respiratory chain.
Also included in this CD is the Desulfovibrio gigas
tungsten formate dehydrogenase, DgW-FDH. In contrast to
Fdh-N, which is a functional heterotrimer, DgW-FDH is a
heterodimer. The DgW-FDH complex is composed of a large
subunit carrying the W active site and one [4Fe-4S]
center, and a small subunit that harbors a series of
three [4Fe-4S] clusters as well as a putative vacant
binding site for a fourth cluster. The smaller subunit
is not included in this alignment. Members of the
MopB_Formate-Dh-Na-like CD belong to the
molybdopterin_binding (MopB) superfamily of proteins.

>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].
