Two additional carbohydrate-binding sites of beta-amylase from Bacillus cereus var. mycoides are involved in hydrolysis and raw starch-binding.

Abstract excerpt

In the previous X-ray crystallographic study, it was found that beta-amylase from Bacillus cereus var. mycoides has three carbohydrate-binding sites aside from the active site: two (Site2 and Site3) in domain B and one (Site1) in domain C. To investigate the roles of these sites in the catalytic reaction and raw starch-binding, Site1 and Site2 were mutated. From analyses of the raw starch-binding of wild-type and...
