Enzyme Information
| 5.4.3.3 |
Lysine 5,6-aminomutase.
based on mapping to UniProt E3PRJ4
(1) (3S)-3,6-diaminohexanoate = (3S,5S)-3,5-diaminohexanoate. (2) D-lysine = 2,5-diaminohexanoate.
-!- This enzyme is a member of the 'AdoMet radical' (radical SAM) family. -!- A 5'-deoxyadenosyl radical is generated during the reaction cycle by reductive cleavage of adenosylcobalamin, which is regenerated at the end of the reaction. -!- Formerly EC 5.4.3.4.
