Maltodextrin phosphorylase
Bacterial enzyme, type of phosphorylase
Maltodextrin phosphorylase is a phosphorylase enzyme (EC 2.4.1.1), more specifically one type of glycosyltransferase (EC 2.4). Maltodextrin phosphorylase plays a critical role in maltodextrin metabolism in E. coli. This bacterial enzyme, often referred to as MalP, catalyzes the phosphorolysis of an α-1,4-glycosidic bond in maltodextrins, removing the non-reducing glucosyl residues of linear oligosaccharides as glucose-1-phosphate (Glc1P). Phosphorylases are well-regarded for their allosteric effects on metabolism, however MalP exhibits no allosteric properties. It has a higher affinity for linear oligosaccharides than the related glycogen phosphorylase.[1]
