The enzymatic synthesis of the actinomycin chromophore also has been described (Weissbach and Katz, 1961 Katz and Weissbach 1962 Salzman, Weissbach and Katz, unpublished results). An enzyme, designated phenoxa-zinone synthetase, was obtained from sonic extracts of S. antihioticus and was shown to catalyze the oxidative condensation of o-aminophenols to the corresponding phenoxazinone. When 3-hydroxy-4-methylanthranilic acid (4MHAA) was used as substrate, actinocin was synthesized. The enzyme has been purified approximately 25- to 30-fold from sonic or French pressure cell extracts of the organism by means of standard protein fractionation procedures (ammonium... [Pg.309]
