STRINGSTRING
STR3 protein (Saccharomyces cerevisiae) - STRING interaction network
"STR3" - Peroxisomal cystathionine beta-lyase, converts cystathionine into homocysteine 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

STR3Peroxisomal cystathionine beta-lyase, converts cystathionine into homocysteine; may be redox regulated by Gto1p (465 aa)    
Predicted Functional Partners:
CYS4
Cystathionine beta-synthase, catalyzes synthesis of cystathionine from serine and homocysteine, the first committed step in cysteine biosynthesis; responsible for hydrogen sulfide generation; mutations in human ortholog cause homocystinuria (507 aa)
 
  0.997
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)
   
 
  0.994
MCY1
Putative cysteine synthase, localized to the mitochondrial outer membrane (393 aa)
 
  0.989
MET6
Cobalamin-independent methionine synthase, involved in methionine biosynthesis and regeneration; requires a minimum of two glutamates on the methyltetrahydrofolate substrate, similar to bacterial metE homologs; Catalyzes the transfer of a methyl group from 5- methyltetrahydrofolate to homocysteine resulting in methionine formation (767 aa)
   
 
  0.988
MHT1
S-methylmethionine-homocysteine methyltransferase, functions along with Sam4p 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. Also converts S- methylmethionine (SMM) to methionine (324 aa)
   
 
  0.984
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)
   
 
  0.983
MET2
L-homoserine-O-acetyltransferase, catalyzes the conversion of homoserine to O-acetyl homoserine which is the first step of the methionine biosynthetic pathway (486 aa)
   
 
  0.978
SAM4
S-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)
   
 
  0.970
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)
   
 
0.970
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)
