==CATALYTIC CORE OF XYLANASE A==

The three-dimensional structure of native xylanase A from Pseudomonas, flouorescens subspecies cellulosa has been refined at 1.8 A resolution., The space group is P2(1)2(1)2(1) with four molecules in the asymmetric, unit. The final model has an R factor of 0.166 for 103 749 reflections, with the four molecules refined independently. The tertiary structure, consists of an eightfold beta/alpha-barrel, the so-called TIM-barrel fold., The active site is in an open cleft at the carboxy-terminal end of the, beta/alpha-barrel, and the active-site residues are a pair of glutamates, Glu127 on strand 4 and Glu246 on strand 7. Both these catalytic glutamate, residues are found on beta-bulges. An atypically long loop after strand 7, is stabilized by calcium. Unusual features include a non-proline, ...
