Surface display of proteins by sortases in Gram-positive bacteria is crucial for bacterial fitness and virulence. We found a unique gene locus encoding an amylase-binding adhesin AbpA and a sortase B in oral streptococci. AbpA possesses a new distinct C-terminal cell wall sorting signal. We demonstrated that this C-terminal motif is required for anchoring AbpA to cell wall. In vitro and in vivo...
Occurrence of chalkiness is a major problem as it is an important parameter in determining the quality of rice grains. High temperature during the grain filling period results in loose packing starch granules that could be due to the involvement of starch degrading enzymes i.e., amylases. Therefore, two rice genotypes viz., PAU 3699-13-2-1-1 and PR122 were sown at two different dates. Thirty-da...
β-Cyclodextrin glycosyltransferase (β-CGTase) belongs to the α-amylase family of enzymes and converts starch to cyclic oligosaccharides called β-cyclodextrins (β-CD). The β-CGTase from alkalophilic Bacillus sp. N-227 was separately mutagenized to give three site-directed β-CGTase mutants, Y127F, R254F and D355R, that showed enhanced cyclization activity towards a starch substrate from 1.64 to 2...
