title: Phenoxazinone synthetase from Streptomyces antibioticus: multiple activities of the enzyme.
abstract: A procedure for the preparation of relatively large quantities of highly purified phenoxazinone synthetase from Streptomyces antibioticus is described. Enzyme preparations consisted of multiple forms, as determined by polyacrylamide gel electrophoresis. Each of the electrophoretically separable forms catalyzed the oxidation of catechols, ferrocyanide, and ethylenic thiols, in addition to o-aminophenols.
