>gnl|CDD|193524 cd05646, M20_AcylaseI_like, M20 Aminoacylase-I like subfamily.
Peptidase M20 family, Aminoacylase-I like (AcyI-like;
Acylase I; N-acyl-L-amino-acid amidohydrolase; EC
3.5.1.14) subfamily. Acylase I is involved in the
hydrolysis of N-acylated or N-acetylated amino acids
(except L-aspartate) and is considered as a potential
target of antimicrobial agents. Porcine AcyI is also
shown to deacetylate certain quorum-sensing
N-acylhomoserine lactones, while the rat enzyme has been
implicated in degradation of chemotactic peptides of
commensal bacteria. Prokaryotic arginine synthesis
usually involves the transfer of an acetyl group to
glutamate by ornithine acetyltransferase in order to
form ornithine. However, Escherichia coli
acetylornithine deacetylase (acetylornithinase, ArgE)
(EC 3.5.1.16) catalyzes the deacylation of
N2-acetyl-L-ornithine to yield ornithine and acetate.
Phylogenetic evidence suggests that the clustering of
the arg genes in one continuous sequence pattern arose
in an ancestor common to Enterobacteriaceae and
Vibrionaceae, where ornithine acetyltransferase was lost
and replaced by a deacylase.

>gnl|CDD|219017 pfam06418, CTP_synth_N, CTP synthase N-terminus. This family
consists of the N-terminal region of the CTP synthase
protein (EC:6.3.4.2). This family is found in
conjunction with pfam00117 located in the C-terminal
region of the protein. CTP synthase catalyzes the
synthesis of CTP from UTP by amination of the pyrimidine
ring at the 4-position.

>gnl|CDD|232926 TIGR00337, PyrG, CTP synthase. CTP synthase is involved in
pyrimidine ribonucleotide/ribonucleoside metabolism. The
enzyme catalyzes the reaction L-glutamine + H2O + UTP +
ATP = CTP + phosphate + ADP + L-glutamate. The enzyme
exists as a dimer of identical chains that aggregates as
a tetramer. This gene has been found circa 500 bp 5'
upstream of enolase in both beta (Nitrosomonas europaea)
and gamma (E.coli) subdivisions of proteobacterium (FEMS
Microbiol Lett 1998 Aug 1;165(1):153-7) [Purines,
pyrimidines, nucleosides, and nucleotides, Pyrimidine
ribonucleotide biosynthesis].

>gnl|CDD|193550 cd05675, M20_yscS_like, M20 Peptidase, carboxypeptidase yscS-like.
Peptidase M20 family, yscS (GlyX-carboxypeptidase, CPS1,
carboxypeptidase S, carboxypeptidase a, carboxypeptidase
yscS, glycine carboxypeptidase)-like subfamily. This
group contains proteins that have been uncharacterized
to date with similarity to vacuolar proteins involved in
nitrogen metabolism which are essential for use of
certain peptides that are sole nitrogen sources. YscS
releases a C-terminal amino acid from a peptide that has
glycine as the penultimate residue. It is synthesized as
one polypeptide chain precursor which yields two active
precursor molecules after carbohydrate modification in
the secretory pathway. The proteolytically unprocessed
forms are associated with the membrane, whereas the
mature forms of the enzyme are soluble. Enzymes in this
subfamily may also cleave intracellularly generated
peptides in order to recycle amino acids for protein
synthesis.

>gnl|CDD|193495 cd03873, Zinc_peptidase_like, Zinc peptidases M18, M20, M28, and
M42. Zinc peptidases play vital roles in metabolic and
signaling pathways throughout all kingdoms of life. This
family corresponds to several clans in the MEROPS
database, including the MH clan, which contains 4
families (M18, M20, M28, M42). The peptidase M20 family
includes carboxypeptidases such as the glutamate
carboxypeptidase from Pseudomonas, the thermostable
carboxypeptidase Ss1 of broad specificity from archaea
and yeast Gly-X carboxypeptidase. The dipeptidases
include bacterial dipeptidase, peptidase V (PepV), a
eukaryotic, non-specific dipeptidase, and two Xaa-His
dipeptidases (carnosinases). There is also the bacterial
aminopeptidase, peptidase T (PepT) that acts only on
tripeptide substrates and has therefore been termed a
tripeptidase. Peptidase family M28 contains
aminopeptidases and carboxypeptidases, and has
co-catalytic zinc ions. However, several enzymes in this
family utilize other first row transition metal ions
such as cobalt and manganese. Each zinc ion is
tetrahedrally co-ordinated, with three amino acid
ligands plus activated water; one aspartate residue
binds both metal ions. The aminopeptidases in this
family are also called bacterial leucyl aminopeptidases,
but are able to release a variety of N-terminal amino
acids. IAP aminopeptidase and aminopeptidase Y
preferentially release basic amino acids while glutamate
carboxypeptidase II preferentially releases C-terminal
glutamates. Glutamate carbxypeptidase II and plasma
glutamate carboxypeptidase hydrolyze dipeptides.
Peptidase families M18 and M42 contain
metalloaminopeptidases. M18 is widely distributed in
bacteria and eukaryotes. However, only yeast
aminopeptidase I and mammalian aspartyl aminopeptidase
have been characterized in detail. Some of M42 (also
known as glutamyl aminopeptidase) enzymes exhibit
aminopeptidase specificity while others also have
acylaminoacylpeptidase activity (i.e. hydrolysis of
acylated N-terminal residues).
