title: Cloning of a streptomycin-production gene directing synthesis of N-methyl-L-glucosamine.
abstract: A Streptomyces bikiniensis DNA fragment complementing a deficiency in streptomycin (Sm) production was cloned on the plasmid vector pIJ385. Host strain S. bikiniensis SD 1 used as the recipient in cloning displayed deficiency in biosynthesis of N-methyl-L-glucosamine, one of the moieties of Sm. The cloned fragment on the multicopy plasmid pIJ385 conferred sevenfold increase in Sm production in comparison with the wild-type parental strain. By subcloning, the region complementing the Sm deficiency of SD 1 was narrowed to a 3.0-kb fragment.
