| 1.14.20.1 | evolution |
the enzyme is a member of the 2-oxoglutarate oxygenase superfamily, the members have substantially conserved active sites and are proposed to employ a consensus mechanism proceeding via formation of an enzyme·Fe(II)-2OG-substrate ternary complex |
-, 744318 |
| 1.14.20.1 | metabolism |
the enzyme from Acremonium chrysogenum is bifunctional and catalyzes both the synthesis of deacetoxycephalosporin C from penicillin N, EC 1.14.20.1, as well as the hydroxylation of deacetoxycephalosporin C to deacetylcephalosporin C, EC 1.14.11.26. The activities are located on two different domains |

| 1.14.20.1 | physiological function |
Cephalosporium acremonium expandase is a bifunctional enzyme, penicillin expandase, which catalyzes the ring expansion of penicillin N and the hydroxylation of deacetoxycephalosporin C (DAOC) to deacetylcephalosporin C (DAC). 2-oxoglutarate, Fe2+ and O2 are required for its catalytic activity. The enzyme is encoded by gene cefEF |

| 1.14.20.1 | physiological function |
deacetoxycephalosporin C synthase (DAOCS) catalyzes the oxidative ring expansion of penicillin N (penN) to give deacetoxycephalosporin C (DAOC), which is the committed step in the biosynthesis of the clinically important cephalosporin antibiotics. The enzyme from Streptomyces clavuligerus shows an unusual ping-pong mechanism, which is significantly different from other members of the 2OG oxygenase superfamily |
