Enzyme Information
| 4.4.1.21 |
S-ribosylhomocysteine lyase.
based on mapping to UniProt P44007
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.
