Crystal Structure Analysis of Alpha-Amylase from Bacillus Subtilis complexed with Acarbose
Overview
The crystal structure of Bacillus subtilis alpha-amylase, in complex with, the pseudotetrasaccharide inhibitor acarbose, revealed an hexasaccharide, in the active site as a result of transglycosylation. After comparison, with the known structure of the catalytic-site mutant complexed with the, native substrate maltopentaose, it is suggested that the present structure, represents a mimic intermediate in the initial stage of the catalytic, process.
About this Structure
