Nucleotide sequence of the streptomycinphosphotransferase and amidinotransferase genes from Streptomyces griseus.

Genes for streptomycin phosphotransferase and inosamine-P-amidinotransferase from a streptomycin-producing Streptomyces griseus were cloned on a 3.8kb BamHI-SphI fragment in S. lividans using the multicopy cloning vector pIJ702. The nucleotide sequence of this 3.8kb fragment was determined and the coding sequences for the two genes were identified by comparison with the amino-terminal sequences of the two enzymes purified from S. lividans clones.
