Crystal Structure of XynC from Bacillus subtilis 168

Structural highlights

3gtn is a 2 chain structure with sequence from "vibrio_subtilis"_ehrenberg_1835 "vibrio subtilis" ehrenberg 1835. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Gene:	BSU18150, xynC, ynfF ("Vibrio subtilis" Ehrenberg 1835)
Activity:	Glucuronoarabinoxylan endo-1,4-beta-xylanase, with EC number 3.2.1.136
Resources:	FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

[XYNC_BACSU] Catalyzes the depolymerization of methylglucuronoxylan (MeGAXn) from different sources. It cleaves the beta-1,4-xylosidic bond penultimate to that linking carbon one of the xylose residue substituted with alpha-1,2-linked 4-O-methyl-D-glucuronate (MeGA).^[1]

Publication Abstract from PubMed

The recent biochemical characterization of the xylanases of glycosyl hydrolase family 5 (GH 5) has identified a distinctive endo mode of action, hydrolyzing the beta-1,4 xylan chain at a specific site directed by the position of an alpha-1,2-linked glucuronate moiety. Xylanase C (XynC), the GH 5 xylanase from Bacillus subtilis 168, has been cloned, overexpressed and crystallized. Initial data collection was performed and a preliminary model has been built into a low-quality 2.7 A resolution density map. The crystals belonged to the primitive monoclinic space group P2(1). Further screening identified an additive that resulted in large reproducible crystals. This larger more robust crystal form belonged to space group P2(1)2(1)2 and a resulting data set has been processed to 1.64 A resolution. This will be the second structure to be solved from this unique xylanase family and the first from a Gram-positive bacterium. This work may help to identify the structural determinants that allow the exceptional specificity of this enzyme and the role it plays in the biological depolymerization and processing of glucuronoxylan.
