| |
| The room-temperature structure of xylanase (EC 3.2.1.8) from the bacterial plant pathogen Erwinia chrysanthemi expressed in Escherichia coli, a 45 kDa, 413-amino acid protein belonging to glycoside hydrolase family 5, has been determined by multiple isomorphous replacement and refined to a resolution of 1.42 A. This represents the first structure of a xylanase not belonging to either glycoside hydrolase family 10 or family 11. The enzyme is composed of two domains similar to most family 10 xylanases and the alpha-amylases. The catalytic domain (residues 46-315) has a (beta/alpha)(8)-barrel motif with a binding cleft along the C-terminal side of the beta-barrel. The catalytic residues, Glu165 and Glu253, determined by correspondence to other family 5 and family 10 glycoside hydrolases, lie inside this cleft on the C-terminal ends of beta-strands 4 and 7, respectively, with an O(epsilon)2...O(epsilon)1 distance of 4.22 A. The smaller domain (residues 31-43 and 323-413) has a beta(9)-barrel motif with five of the strands interfacing with alpha-helices 7 and 8 of the catalytic domain. The first 13 N-terminal residues form one beta-strand of this domain. Residues 44, 45, and 316-322 form the linkers between this domain and the catalytic domain.
