Reaction

Reaction Comment Organism Reaction ID
isomaltose + h2O = 2 D-glucose The enzyme complex consists of two noncovalently linked subunits. The active site of the sucrase subunit cleaves alpha,beta-(1-2)glycosidic bonds and contains only two subsites and, thus can bind only two monomeric parts of a substrate with positive affinity. The isomaltase cleaves alpha-(1-6) and alpha-(1-1) glycoside bonds Sus scrofa

additional information Additional substrates are mixtures of isomers containing mannitol and glucitol, e.g. alpha-D-glucopyranosyl-(1-6)-alpha-D-glucopyranosyl-(1-1)-D-mannitol and alpha-D-glucopyranosyl-(1-6)-alpha-D-glucopyranosyl-(1-1)-D-glucitol in a ratio 2:3, alpha-D-glucopyranosyl-(1-6)-alpha-D-glucopyranosyl-(1-6)-alpha-D-gluco-pyranosyl-(1-1)-D-mannitol and alpha-D-glucopyranosyl-(1-6)-alpha-D-glucopyranosyl-(1-6)-alpha-D-gluco-pyranosyl-(1-1)-D-glucitol in a ratio 2:3, 1,6-di-O-alpha-D-glucopyranosyl-D-mannitol and 1,6-di-O-alpha-D-glucopyranosyl-D-glucitol, alpha-D-glucopyranosyl-(1-6)-alpha-D-glucopyranosyl-(1-1)-D-mannitol and alpha-D-glucopyranosyl-(1-6)-alpha-D-glucopyranosyl-(1-1)-D-glucitol. The end products are glucose, mannose and glucitol in accordance with the composition of the initial substrate. Sus scrofa ?
