Thermal tolerant mannanase from acidothermus cellulolyticus
View Patent ↗The invention provides a thermal tolerant mannanase that is a member of the glycoside hydrolase family. The invention further discloses this mannanase as ManA. ManA has been isolated and characterized from Acidothermus cellulolyticus . The invention further provides recombinant forms of the identified ManA. Methods of making ManA polypeptides, including fusions, variants, and derivatives, are also disclosed. Methods of using mannanase A, including for the processing of food and for use in food stuffs as bulking agents and the like, are also disclosed.
1. A purified ManA polypeptide molecule capable of degrading mannose comprising:
the sequence of SEQ ID NO:1.
2. A purified ManA polypeptide wherein its encoding nucleotide sequence in the same as SEQ ID NO: 2.
3. A composition comprising the polypeptide molecule of claim 1 and a carrier.
4. A method for reducing hemicellulose in a starting material, the method comprising:
contacting the starting material with an effective amount of polypeptide molecule of claim 1 .
5. An industrial detergent mixture suitable for degrading hemicellulose, said mixture comprising a purified ManA polypeptide having the sequence of SEQ ID NO. 1.
6. The industrial detergent mixture of claim 5 , wherein said purified ManA polypeptide is further defined as having its encoding nucleotide sequence the same as SEQ ID NO:2.
