STRINGSTRING
STRING protein interaction network
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

pepD1Xaa-His dipeptidase, also known as aminoacyl-histidine dipeptidase, catalyzes the hydrolysis of Xaa-|-His dipeptides. This dipeptidase has specificity for the unusual dipeptide beta-alanyl-L-histidine. PepD binds two co-catalytic zinc ions that activate the catalytic water molecule; Belongs to the family M20 of the metallopeptidase; Localized in the cytoplasm; High confidence in function and specificity. (481 aa)

ggtA
Gamma-glutamyltranspeptidase, family T3; Gamma-glutamyltranspeptidase is a threonine peptidase that catalyzes the transfer of the gamma-glutamyl moiety of glutathione to an acceptor that may be an amino acid, a peptide or water (forming glutamate). GgtA plays a key role in the gamma-glutamyl cycle, a pathway for the synthesis and degradation of glutathione. This enzyme consists of two polypeptide chains, a heavy and a light subunit, processed from a single chain precursor; Belongs to the family T3 of the peptidases; Putative lipoprotein signal peptide cleaved between the residues 19 an [...]

pepD2
Xaa-His dipeptidase, also known as aminoacyl-histidine dipeptidase, catalyzes the hydrolysis of Xaa-|-His dipeptides. This dipeptidase has specificity for the unusual dipeptide beta-alanyl-L-histidine. Belongs to the family M20 of the metallopeptidase. PepD binds two co-catalytic zinc ions, which are coordinated by five conserved residues (His/Asp, Asp, Glu, Glu/Asp, His). The zinc ions stabilize the tetrahedral intermediate and activate the catalytic water molecule. Localized in the cytoplasm; High confidence in function and specificity.

CAZ95294.1
Aminopeptidase, family M1; Aminopeptidase catalyzes the hydrolysis of N-terminal amino-acid residues from oligopeptides or polypeptides. This enzyme belongs to the family M1 of the peptidases. A catalytic zinc ion is bound by two histidines and a glutamate. The histidines are within an 'HEXXH' motif on one long helix with the glutamate on another antiparallel helix. The catalytic mechanism is believed to involve activation of a water molecule by the zinc ion. The glutamate of the HEXXH motif is known to be important for catalysis and a tyrosine may also be involved. Features a signal p [...]

aatB
Aspartate aminotransferase or Transaminase A or Glutamic-aspartic transaminase or Glutamic-oxaloacetic transaminase converts the L-aspartic acid and the 2-oxoglutarate into L-glutamate and oxaloacetate using the Pyridoxal phosphate as cofactor bound by covalent linkage to a lysine residue; Belongs to the class-I pyridoxal-phosphate-dependent aminotransferase family; Localized in the cytoplasm; High confidence in function and specificity.

glyA
Serine hydroxymethyltransferase; Catalyzes the reversible interconversion of serine and glycine with tetrahydrofolate (THF) serving as the one-carbon carrier. This reaction serves as the major source of one-carbon groups required for the biosynthesis of purines, thymidylate, methionine, and other important biomolecules. Also exhibits THF-independent aldolase activity toward beta-hydroxyamino acids, producing glycine and aldehydes, via a retro-aldol mechanism.
