Ticub Hydroxyproline and altohydroxyproline, from actinomycins X o a and X o B , respectively, were distinguished by HVE16’28. This separation can also be effected by GLC72. The latter technique was employed to distinguish c i b - and thanb-4-methylproline in the actinomycins Klc, KzC and Kit, KZt, respectively+ The two diastereoisomers of 4 - h y d r o x y - 5 - m e t h y l p r o l i n e resulting from aluminum isopropoxide reduction of 4-keto-5methylproline in intact actinomycins Z 1 and 25 were distinguished b high-voltage paper electrophoresis, but were not identified 5zy73.
