== Function == Phosphorylases should not be confused with phosphatases, which remove phosphate groups. In more general terms, phosphorylases are enzymes that catalyze the addition of a phosphate group from an inorganic phosphate (phosphate + hydrogen) to an acceptor, not to be confused with a phosphatase (a hydrolase) or a kinase (a phosphotransfe...

(fos-for´ә-lās) any of a group of enzymes important in the breakdown of glycosides because they catalyze the sequential cleavage of glycosyl groups from the ends of long chains in glycosides. After cleaving a glycosyl group off the glycoside, they link the cleaved glycosyl group to an inorganic phosphat...
