Abstract
Deacetoxycephalosporin C synthetase is provided in purified form via chromatography of crude cell-free extracts over a weak anion exchange resin followed by gel filtration and hydroxylapatite chromatography, all carried out in the presence of glycerol, a C.sub.1 -C.sub.3 alkyl monohydric alcohol, e.g., ethanol, a sulfhydryl containing reducing agent, e.g., dithiothreitol, and ascorbate. The purified enzyme which possesses both expandase and hydroxylase activities can be further purified by chromatography over a strong anion exchange resin.
