Abstract excerpt
Endo-1,5-α-L-arabinanases are glycosyl hydrolases that are able to cleave the glycosidic bonds of α-1,5-L-arabinan, releasing arabino-oligosaccharides and L-arabinose. Two extracellular endo-1,5-α-L-arabinanases have been isolated from Bacillus subtilis, BsArb43A and BsArb43B (formally named AbnA and Abn2, respectively). BsArb43B shows low sequence identity with previously characterized 1,5-α-L-arabinanases and...
