title: [Actinomyces streptomycini mutant blocked in streptidine biosynthesis].
abstract: Mutant 170 not capable of forming streptidine and streptomycin was obtained using chemical mutagenes. This mutant can produce streptomycin only with suplementation of exogenous streptidine. Experiment with labeled C14-streptidine showed its specific incorporation in streptidine moiety of streptomycin molecule.
