Crystal structure of CBM31 from beta-1,3-xylanase

Overview

Here, we present the crystal structure of the family 31, carbohydrate-binding module (CBM) of beta-1,3-xylanase from Alcaligenes, sp. strain XY-234 (AlcCBM31) determined at a resolution of 1.25A. The, AlcCBM31 shows affinity with only beta-1,3-xylan. The AlcCBM31 molecule, makes a beta-sandwich structure composed of eight beta-strands with a, typical immunoglobulin fold and contains two intra-molecular disulfide, bonds. The folding topology of AlcCBM31 differs from that of the large, majority of other CBMs, in which eight beta-strands comprise a, beta-sandwich structure with a typical jelly-roll fold. AlcCBM31 shows, structural similarity with CBM structures of family 34 and family 9, which, also adopt structures based on immunoglobulin folds.
