STRINGSTRING
SAM4 protein (Saccharomyces cerevisiae) - STRING interaction network
"SAM4" - S-adenosylmethionine-homocysteine methyltransferase, functions along with Mht1p in the conversion of S-adenosylmethionine in Saccharomyces cerevisiae
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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

SAM4S-adenosylmethionine-homocysteine methyltransferase, functions along with Mht1p in the conversion of S-adenosylmethionine (AdoMet) to methionine to control the methionine/AdoMet ratio; Homocysteine S-methyltransferase involved in the conversion of S-adenosylmethionine (AdoMet) to methionine to control the methionine/AdoMet ratio. Converts also S- methylmethionine (SMM) to methionine (325 aa)    
Predicted Functional Partners:
SAM1
S-adenosylmethionine synthetase, catalyzes transfer of the adenosyl group of ATP to the sulfur atom of methionine; one of two differentially regulated isozymes (Sam1p and Sam2p); Catalyzes the formation of S-adenosylmethionine from methionine and ATP (382 aa)
   
 
  0.985
SAM2
S-adenosylmethionine synthetase, catalyzes transfer of the adenosyl group of ATP to the sulfur atom of methionine; one of two differentially regulated isozymes (Sam1p and Sam2p); Catalyzes the formation of S-adenosylmethionine from methionine and ATP (384 aa)
       
  0.978
SAH1
S-adenosyl-L-homocysteine hydrolase, catabolizes S-adenosyl-L-homocysteine which is formed after donation of the activated methyl group of S-adenosyl-L-methionine (AdoMet) to an acceptor; Adenosylhomocysteine is a competitive inhibitor of S- adenosyl-L-methionine-dependent methyl transferase reactions; therefore adenosylhomocysteinase may play a key role in the control of methylations via regulation of the intracellular concentration of adenosylhomocysteine (449 aa)
     
 
  0.977
STR2
Cystathionine gamma-synthase, converts cysteine into cystathionine; Catalyzes the formation of L-cystathionine from O- succinyl-L-homoserine (OSHS) and L-cysteine, via a gamma- replacement reaction. In the absence of thiol, catalyzes gamma- elimination to form 2-oxobutanoate, succinate and ammonia (By similarity) (639 aa)
   
 
  0.974
STR3
Peroxisomal cystathionine beta-lyase, converts cystathionine into homocysteine; may be redox regulated by Gto1p (465 aa)
   
 
  0.970
YLL058W
Putative protein of unknown function with similarity to Str2p, which is a cystathionine gamma-synthase important in sulfur metabolism; YLL058W is not an essential gene; Catalyzes the formation of L-cystathionine from O- succinyl-L-homoserine (OSHS) and L-cysteine, via a gamma- replacement reaction. In the absence of thiol, catalyzes gamma- elimination to form 2-oxobutanoate, succinate and ammonia (By similarity) (575 aa)
   
 
  0.967
IRC7
Beta-lyase involved in the production of thiols; null mutant displays increased levels of spontaneous Rad52p foci; expression induced by nitrogen limitation in a GLN3, GAT1-dependent manner and by copper levels in a Mac1-dependent manner (340 aa)
   
 
  0.964
YML082W
Putative protein predicted to have carbon-sulfur lyase activity; transcriptionally regulated by Upc2p via an upstream sterol response element; green fluorescent protein (GFP)-fusion protein localizes to the nucleus and the cytoplasm; YML082W is not /.../ential gene; Catalyzes the formation of L-cystathionine from O- succinyl-L-homoserine (OSHS) and L-cysteine, via a gamma- replacement reaction. In the absence of thiol, catalyzes gamma- elimination to form 2-oxobutanoate, succinate and ammonia (By similarity) (649 aa)
   
 
  0.962
MET17
O-acetyl homoserine-O-acetyl serine sulfhydrylase; required for Methionine and cysteine biosynthesis; Transforms O-acetylhomoserine into homocysteine and O- acetylserine into cysteine (444 aa)
         
  0.927
CYS3
Cystathionine gamma-lyase, catalyzes one of the two reactions involved in the transsulfuration pathway that yields cysteine from homocysteine with the intermediary formation of cystathionine (394 aa)
