sucrose + phosphate = D-fructose + alpha-D-glucose 1-phosphate | a two-step catalytic mechanism: Asp192 is the catalytic nucleophile, Glu232 is the catalytic acid-base, and Asp290 functions as a transition state stabilizer. By forming a strong hydrogen bond with the hydroxyl groups at C2 and C3 of the glucosyl residue being transferred, the anionic side chain of Asp290 is suggested to provide selective stabilization to oxocarbenium ion-like transition states flanking the covalent alpha-glucosyl enzyme intermediate | Bifidobacterium adolescentis | |
sucrose + phosphate = D-fructose + alpha-D-glucose 1-phosphate | sucrose phosphorylase catalyzes glucosyl transfer with retention of the alpha-anomeric configuration of the donor substrate in the resulting glucosidic product, double displacement-like catalytic mechanism | Leuconostoc mesenteroides | |
