- S-ribosylhomocysteine lyase
enzymology, a S-ribosylhomocysteine lyase (EC number|188.8.131.52) is an enzymethat catalyzes the chemical reaction
:S-(5-deoxy-D-ribos-5-yl)-L-homocysteine L-homocysteine + (4S)-4,5-dihydroxypentan-2,3-dione
Hence, this enzyme has one substrate,
S-(5-deoxy-D-ribos-5-yl)-L-homocysteine, and two products, L-homocysteineand (4S)-4,5-dihydroxypentan-2,3-dione.
This enzyme belongs to the family of
lyases, specifically the class of carbon-sulfur lyases. The systematic name of this enzyme class is S-(5-deoxy-D-ribos-5-yl)-L-homocysteine L-homocysteine-lyase [(4S)-4,5-dihydroxypentan-2,3-dione-forming] . Other names in common use include S-ribosylhomocysteinase, and LuxS. This enzyme participates in methionine metabolism.
CAS registry numberfor this enzyme class is CAS registry|37288-63-4."
