phosphorylases


phos·phor·y·las·es

(fos-fōr'i-lās'ĕz), 1. General term for enzymes transferring a phosphoryl group to some organic acceptor, hence belonging to the transferases. 2. Specifically, enzymes that release a single glucosyl residue from a polyglucose as d-glucose 1-phosphate, the phosphate coming from orthophosphate; for example, phosphophorylase, sucrose phosphorylases, cellobiose phosphorylases.
