R 3.-.-.- : Transfer (bond cleavage and new bond formation) (Reaction)

L 3.900.-.- : Glycosyl group from Hydroxyl oxygen to Hydroxyl oxygen (Ligand group involved)

Catalytic mechanisms

  • 3.900.45300.- : Anhydrosialidase-like mechanism (Acid-Base-Stabilizer/Stabilizer/Modulator); SN1-like reaction; Modulator assists bond cleavage between transferred group and leaving group; Acid protonation to leaving group leads to departure of leaving group; Intermediate (transferred group) stabilized; Base-activation of acceptor group; Activated acceptor attacks on transferred group

  • 3.900.275800.- : Cyclodextrin-glycosyltransferase-like mechanism (Nucleophile/Acid-Base/Stabilizer-Modulator); SN1-like reaction; Modulator-assisted acid protonation to leaving group; Transition-state stabilized; Nucleophile attacks on transferred group; Covalent intermediate formation; Base deprotonation of acceptor group; Modulator-assisted acid protonation to leaving group again; Transition-state stabilized; Acceptor group attacks on transferred group
