Superfamily S-ribosylhomocysteinase (LuxS)
Functional Family S-ribosylhomocysteine lyase

Enzyme Information

4.4.1.21
S-ribosylhomocysteine lyase.
based on mapping to UniProt Q8Z4D7
S-(5-deoxy-D-ribos-5-yl)-L-homocysteine = L-homocysteine + (4S)-4,5- dihydroxypentan-2,3-dione.
-!- The 4,5-dihydroxypentan-2,3-dione formed spontaneously cyclizes and combines with borate to form an autoinducer (AI-2) in the bacterial quorum-sensing mechanism, which is used by many bacteria to control gene expression in response to cell density. -!- Formerly EC 3.2.1.148 and EC 3.3.1.3.
