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

Score
cysKCysteine synthase A; Identified by match to protein family HMM PF00291; match to protein family HMM TIGR01136; match to protein family HMM TIGR01139; Belongs to the cysteine synthase/cystathionine beta- synthase family. (310 aa)    
Predicted Functional Partners:
cysE-1
Serine acetyltransferase; Identified by similarity to SP:P74089; match to protein family HMM PF00132; match to protein family HMM TIGR01172.
 
 0.982
metZ
O-succinylhomoserine sulfhydrylase; Catalyzes the formation of L-homocysteine from O-succinyl-L- homoserine (OSHS) and hydrogen sulfide.
 0.980
cysE-2
Serine acetyltransferase; Identified by match to protein family HMM PF00132; match to protein family HMM TIGR01172.
 
 0.980
MCA1436
Putative serine acetyltransferase CysE; Identified by similarity to SP:P71405; match to protein family HMM PF00132.
 
 0.978
MCA1021
Aminotransferase, classes I and II; Identified by match to protein family HMM PF00155.
    
 0.955
MCA0431
Flavodoxin domain protein; Component of the sulfite reductase complex that catalyzes the 6-electron reduction of sulfite to sulfide. This is one of several activities required for the biosynthesis of L-cysteine from sulfate. The flavoprotein component catalyzes the electron flow from NADPH -> FAD -> FMN to the hemoprotein component.

MCA2059
Nitrite/sulfite reductase protein; Identified by match to protein family HMM PF01077; match to protein family HMM PF03460.
  
 
 0.939
serC
Phosphoserine aminotransferase; Catalyzes the reversible conversion of 3- phosphohydroxypyruvate to phosphoserine and of 3-hydroxy-2-oxo-4- phosphonooxybutanoate to phosphohydroxythreonine; Belongs to the class-V pyridoxal-phosphate-dependent aminotransferase family. SerC subfamily.
  
 
 0.924
MCA1800
Putative oxidoreductase; Identified by similarity to GP:19879585; match to protein family HMM PF07992.
     
 0.904
MCA2202
Aspartate aminotransferase; Identified by similarity to SP:P23034; match to protein family HMM PF00155.
