UniProt functional annotation for Q08751

UniProt code: Q08751.

Organism: Thermoactinomyces vulgaris.
Taxonomy: Bacteria; Firmicutes; Bacilli; Bacillales; Thermoactinomycetaceae; Thermoactinomyces.
 
Function: Hydrolyzes pullulan efficiently but only a small amount of starch. Endohydrolysis of 1,4-alpha-glucosidic linkages in pullulan to form panose. Cleaves also (1-6)-alpha-glucosidic linkages to form maltotriose. {ECO:0000269|PubMed:7763540}.
 
Catalytic activity: Reaction=Hydrolysis of pullulan to panose (6-alpha-D-glucosylmaltose).; EC=3.2.1.135; Evidence={ECO:0000269|PubMed:7763540};
Cofactor: Name=Ca(2+); Xref=ChEBI:CHEBI:29108; Evidence={ECO:0000269|PubMed:12051850}; Note=Binds 1 Ca(2+) ion per subunit. {ECO:0000269|PubMed:12051850};
Subunit: Monomer.
Similarity: Belongs to the glycosyl hydrolase 13 family. {ECO:0000305}.
