Enzymatic Synthesis of Glycosides Using the beta-Galactosidase of Escherichia coli: Regio- and Stereo-chemical Studies
beta-Galactosyl transfer from lactose to acceptor alcohols (R)-(-)-butan-2-ol, (RS)-butan-2-ol, (S)-(+)-propane-1,2-diol, (RS)-propane-1,2-diol, (S)-(+)-butane-1,3-diol, (RS)-butane-1,3-diol, propane-1,3-diol, (S)-(+)-isopropylideneglycerol (1,2-O-isopropylidene-sn-glycerol) and (RS)-isopropylideneglycerol (rac-1,2-O-isopropylideneglycerol) was studied, catalysed by the beta-galactosidase (beta-D-galactoside galactohydrolase EC 3.2.1.23) of Escherichia coli.Preference for galactosyl transfer to the R-enantiomers of chiral alcohols was observed, although selectivity was not pronounced.Higher selectivity for transfer to the primary hydroxy groups of the primary-secondary diols was observed.The results are interpreted in terms of a proposed active site model for the enzyme.
Electric Literature of 4254-15-3, Each elementary reaction can be described in terms of its molecularity, the number of molecules that collide in that step. The slowest step in a reaction mechanism is the rate-determining step.you can also check out more blogs about Electric Literature of 4254-15-3
