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

metBCystathionine gamma-synthase MetB (CGS) (O-succinylhomoserine [thiol]-lyase); Catalyzes the formation of L-cystathionine from O-succinyl-L- homoserine (OSHS) and L-cysteine, via a gamma-replacement reaction (By similarity). In the absence of thiol, catalyzes gamma-elimination to form 2-oxobutanoate, succinate and ammonia. (388 aa)    
Predicted Functional Partners:
cbs
Probable cystathionine beta-synthase Cbs (serine sulfhydrase) (beta-thionase) (hemoprotein H-450); Rv1077, (MTV017.30), len: 464 aa. Probable cbs (previously cysM2), cystathionine beta-synthase, similar throughout its length to many eukaryotic cystathionine beta-synthases e.g. P32232|CBS_RAT cystathionine beta-synthase (560 aa), FASTA scores: opt: 951, E(): 0,(40.2% identity in 450 aa overlap); also similar in N-terminal domain (aa 1 - 330) to Rv2334|MTCY98.03 CysK Mycobacterium tuberculosis (310 aa), FASTA scores: opt: 855, E(): 0, (46.8% identity in 314 overlap); and other cysteine s [...]

metH
Methionine synthase; Catalyzes the transfer of a methyl group from methyl- cobalamin to homocysteine, yielding enzyme-bound cob(I)alamin and methionine. Subsequently, remethylates the cofactor using methyltetrahydrofolate (By similarity); Belongs to the vitamin-B12 dependent methionine synthase family.
  
 
 0.987
metE
5-methyltetrahydropteroyltriglutamate--homocysteine methyltransferase; Catalyzes the transfer of a methyl group from 5- methyltetrahydrofolate to homocysteine resulting in methionine formation; Belongs to the vitamin-B12 independent methionine synthase family.
  
 
 0.977
ilvE
Branched-chain amino acid transaminase IlvE; Catalyzes the reversible transfers of an amino group from glutamate to the alpha-ketoacid of the respective amino acid in the final step in the biosynthesis of branchedchain amino acids. The amino acids can be ranked in the following order with respect to their efficiency as amino donor: Leu > Ile > Val. Belongs to the class-IV pyridoxal-phosphate-dependent aminotransferase family.
  
 0.972
cysK1
O-acetylserine sulfhydrylase; Catalyzes the conversion of O-acetylserine (OAS) to cysteine through the elimination of acetate and addition of hydrogen sulfide. Belongs to the cysteine synthase/cystathionine beta- synthase family.
  
 0.971
sirA
Ferredoxin-dependent sulfite reductase SirA; Catalyzes the reduction of sulfite to sulfide, a step in the biosynthesis of sulfur-containing amino acids and cofactors. Belongs to the nitrite and sulfite reductase 4Fe-4S domain family.
