摘要

Cysteines 100, 155, and 197 of recombinant deacetoxycephalosporin C synthase were mutated to alanine residues. The C100A mutant had properties similar to those of the wild-type enzyme, but mutation of Cys-155 and Cys-197 reduced enzyme activity with penicillin N and penicillin G to different extents.
