Thus, the two substrates of this enzyme are ATP and streptomycin, whereas its two products are ADP and streptomycin 6-phosphate.
This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing groups (phosphotransferases) with an alcohol group as acceptor. The systematic name of this enzyme class is ATP:streptomycin 6-phosphotransferase. Other names in common use include streptidine kinase, SM 6-kinase, streptomycin 6-kinase (phosphorylating), streptidine kinase (phosphorylating), streptomycin 6-O-phosphotransferase, and streptomycin 6-phosphotransferase.
This enzyme participates in streptomycin biosynthesis when it acts on streptidine. It participates in streptomycin resistance when it acts on the analogous position of streptomycin.[1]
