High-resolution native and complex structures of thermostable beta-mannanase from Thermomonospora fusca - substrate specificity in glycosyl hydrolase family 5. Structure, 6:1433-1444, 1998 Cited by PubMed Abstract: . beta-Mannanases hydrolyse the O-glycosidic bonds in mannan, a hemicellulose constituent of plants. These enzymes have potential use in pulp and paper production and are of significant biotechnological interest. Thermostable beta-mannanases would be particularly useful due to their high temperature optimum and broad pH tolerance. The thermophilic actinomycete Thermomonospora fusca secretes at least one beta-mannanase (molecular mass 38 kDa) with a temperature optimum of 80 degreesC. No three-dimensional structure of a mannan-degrading enzyme has been reported until now. PubMed: 9817845DOI: 10.1016/S0969-2126(98)00142-7 PDB entries with the same primary citation |
