Thus, the two substrates of this enzyme are 1-guanidino-1-deoxy-scyllo-inositol 4-phosphate and H2O, whereas its two products are 1-guanidino-1-deoxy-scyllo-inositol and phosphate.
This enzyme belongs to the family of hydrolases, specifically those acting on phosphoric monoester bonds. The systematic name of this enzyme class is 1-guanidino-1-deoxy-scyllo-inositol-4-phosphate 4-phosphohydrolase. Other names in common use include 1-guanidino-scyllo-inositol 4-phosphatase, and 1-guanidino-1-deoxy-scyllo-inositol-4-P phosphohydrolase.
