Protein
Putative cystathionine gamma-synthase YML082W
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Function
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).
Similarity
Belongs to the trans-sulfuration enzymes family. MET7 subfamily.
