    . 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.
