The enzyme shows reverse phosphorolysis using various carbohydrate acceptor substrates and beta-D-glucose 1-phosphate as the donor, schematic reaction mechanism of reversible phosphorolysis with Glu484 being the general acid catalyst of MalP, overview. For reverse phosphorolysis, the enzyme shows strong preference for monosaccharide acceptors with equatorial 3-OH and 4-OH, such as glucose and mannose. The enzyme also reacts with 2-deoxy glucosamine and 2-deoxy-N-acetylglucosamine, but shows no activity with di- and trisaccharides. Loop 3 of MalP, involved in substrate recognition, blocks the binding of candidate acceptors larger than monosaccharides, molecular modelling, overview. MalP efficiently catalyses the synthesis of several alpha-glucosidic disaccharides, i.e. of alpha-Glc-phosphate-(1,4)-Glc-phosphate, alpha-Glc-phosphate-(1,4)-GlcN-phosphate, alpha-Glc-phosphate-(1,4)-GlcNAc-phosphate, alpha-Glc-phosphate-(1,4)-Man-phosphate, alpha-Glc-phosphate-(1,4)-Xyl-phosphate and alpha-Glc-phosphate-(1,4)-l-Fuc-phopshate, determined by NMR and mass spectrometry, overview.

Salisediminibacterium selenitireducens
Bsel2056 phosphorolyzes only maltose with inversion of the anomeric configuration releasing beta-D-glucose 1-phosphate and D-glucose. Bsel2056 does not cleave the maltose in the absence of inorganic phosphate. In addition, maltooligosaccharides of degree of polymerization 3-6 are not substrate for Bsel2056. But Bsel2056 shows the flexibility for monosaccharide acceptors with alternative C2 substituent, e.g. 2-amino-2-deoxy-D-glucose, 2-deoxy-D-arabino-hexose, 2-acetamido-2-deoxy-D-glucose, and D-mannose, in the reverse reaction resulting in production of 1,4-alpha-D-glucosyl disaccharides with strict regioselectivity. Bsel2056 possesses a binding space to accommodate the bulky C2 substituent of D-glucose. Substrate specificity and product analysis using NMR, overview
