Biosynthesis of unnatural cephalosporins |
| abstract |
ABSTRACT OF THE DISCLOSURE A process for converting a peptide precursor of the ACV type, in which the valine moiety may be replaced by any readily available amino acid,to an unnatural cephalosporin of the type where Rl is H, lower alkyl or functionalizied carboxylic group and R2 is H or lower alkyl,in which the precursor is reacted with cyclase, epimerase and a ring expansion enzyme isolated from a cell-free extract of a prokaryotic organism such as Streptomyces clavuligerus. The three enzymes may be immobilized on a suitable support medium and the conversion may be carried out in a continuous mode. |
