5.1.1.15 |
| Description |
2-aminohexano-6-lactam racemase |
| Alternative names |
2-amino-hexano-6-lactam racemase;
Alpha-amino-epsilon-caprolactam racemase;
Aminocaprolactam racemase;
ACL racemase. |
| Catalyzed reaction |
L-2-aminohexano-6-lactam = D-2-aminohexano-6-lactam. |
| Cofactor |
Pyridoxal-phosphate. |
| Comments |
-!- Also interconverts 2-aminopentano-5-lactam (alpha-amino-delta-valerolactam) and 2-amino-4-thiahexano-6-lactam (where S replaces CH(2) of C-4).
-!- It does not catalyse the racemisation of alpha-amino acids but has some transaminase activity with them. |
