THE THREE-DIMENSIONAL CRYSTAL STRUCTURE OF THE CATALYTIC CORE OF CELLOBIOHYDROLASE I FROM TRICHODERMA REESEITHE THREE-DIMENSIONAL CRYSTAL STRUCTURE OF THE CATALYTIC CORE OF CELLOBIOHYDROLASE I FROM TRICHODERMA REESEI

Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedCellulose is the major polysaccharide of plants where it plays a predominantly structural role. A variety of highly specialized microorganisms have evolved to produce enzymes that either synergistically or in complexes can carry out the complete hydrolysis of cellulose. The structure of the major cellobiohydrolase, CBHI, of the potent cellulolytic fungus Trichoderma reesei has been determined and refined to 1.8 angstrom resolution. The molecule contains a 40 angstrom long active site tunnel that may account for many of the previously poorly understood macroscopic properties of the enzyme and its interaction with solid cellulose. The active site residues were identified by solving the structure of the enzyme complexed with an oligosaccharide, o-iodobenzyl-1-thio-beta-cellobioside. The three-dimensional structure is very similar to a family of bacterial beta-glucanases with the main-chain topology of the plant legume lectins. The three-dimensional crystal structure of the catalytic core of cellobiohydrolase I from Trichoderma reesei.,Divne C, Stahlberg J, Reinikainen T, Ruohonen L, Pettersson G, Knowles JK, Teeri TT, Jones TA Science. 1994 Jul 22;265(5171):524-8.
