Abstract
Xylanase J of alkaliphilic Bacillus sp. strain 41M-1 contains a carbohydrate-binding module family 36 xylan-binding domain (XBD). Mutational analysis of the XBD revealed that Tyr237, Asp313, Trp317, and Asp318 were involved in Ca(2+)-dependent xylan-binding, and that Asp313 and Asp318 were especially important.
