evolution
-
the enzyme belongs to the family of 2-oxoglutarate-dependent oxygenases
-
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
metabolism
two enzymes, deacetoxycephalosporin C synthase and deacetoxycephalosporin C hydroxylase, are involved in the conversion of penicillin N into deacetylcephalosporin C in Streptomyces clavuligerus
metabolism
deacetylcephalosporin C synthase (DACS) transforms an inert methyl group of deacetoxycephalosporin C (DAOC) into an active hydroxyl group of deacetylcephalosporin C (DAC) during the biosynthesis of cephalosporins

the enzyme is involved in the biosynthesis of cephalosporins, it carries out a critical transformation of an inert cephem methyl group of deacetoxycephalosporin C (DAOC) into an active hydroxyl group of deacetylcephalosporin C (DAC) in the presence of iron, oxygen, ascorbic acid, and 2-oxoglutarate. It is a step which is chemically difficult to accomplish and which offers a second substitution site for derivatization in cephalosporins
