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

metAAHomoserine O-succinyltransferase; Transfers an acetyl group from acetyl-CoA to L-homoserine, forming acetyl-L-homoserine. Utilizes a ping-pong kinetic mechanism in which the acetyl group of acetyl-CoA is initially transferred to the enzyme to form an acetyl-enzyme intermediate before subsequent transfer to homoserine to form the final product, O-acetylhomoserine. Has weak activity with succinyl-CoA as the acyl donor. Belongs to the MetA family. (304 aa)    
Predicted Functional Partners:
TM_0882
O-acetylhomoserine sulfhydrylase; Catalyzes the production of homocysteine from O- acetylhomoserine (OAH) and hydrogen sulfide (H2S), a step in the methionine biosynthesis pathway. Is not able to form cystathionine from O-acetylhomoserine and L-cysteine; Belongs to the trans-sulfuration enzymes family.

aar
Cystathionine gamma-synthase; Catalyzes the racemization of L-alanine to D-alanine, and of L-glutamate to D-glutamate. The activity is low, but likely physiological since T.maritima lacks canonical alr and murI genes, while D-alanine and D-glutamate are essential components of peptidoglycan. Also displays a more efficient cystathionine beta-lyase (CBL) activity, cleaving cystathionine to homocysteine and pyruvate; however, this reaction seems not to be physiologically relevant since T.maritima possesses an O-acetyl-homoserine thiolase (MetY) that bypasses the need of CBL for methionine [...]
