| Accepted name: |
N-(5-amino-5-carboxypentanoyl)-L-cysteinyl-D-valine synthase |
| Reaction: |
3 ATP + L-2-aminohexanedioate + L-cysteine + L-valine + H2O = 3 AMP + 3 diphosphate + N-[L-5-amino-5-carboxypentanoyl]-L-cysteinyl-D-valine |

| Other name(s): |
L-δ-(α-aminoadipoyl)-L-cysteinyl-D-valine synthetase; ACV synthetase; L-α-aminoadipyl-cysteinyl-valine synthetase; |
| Systematic name: |
L-2-aminohexanedioate:L-cysteine:L-valine ligase (AMP-forming, valine-inverting) |
| Comments: |
Requires Mg2+. The enzyme contains 4′-phosphopantetheine, which may be involved in the mechanism of the reaction. Forms part of the penicillin biosynthesis pathway (for pathway, click here). |
