- ATP + streptomycin ADP + streptomycin 3"-phosphate
Thus, the two substrates of this enzyme are ATP and streptomycin, whereas its two products are ADP and streptomycin 3''-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 3"-phosphotransferase. Other names in common use include streptomycin 3"-kinase (phosphorylating), and streptomycin 3"-phosphotransferase.
