Thus, the two substrates of this enzyme are ATP and 1-amino-1-deoxy-scyllo-inositol, whereas its two products are ADP and 1-amino-1-deoxy-scyllo-inositol 4-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:1-amino-1-deoxy-scyllo-inositol 4-phosphotransferase. Other names in common use include scyllo-inosamine kinase (phosphorylating), scyllo-inosamine kinase, and ATP:inosamine phosphotransferase. This enzyme participates in streptomycin biosynthesis.
