Secondary Accession Numbers None
Name Alpha-amylase 1C
Synonyms Not Available
Gene Name AMY1C
Protein Type Unknown
Biological Properties
General Function Not Available
Specific Function Calcium-binding enzyme that initiates starch digestion in the oral cavity (PubMed:12527308). Catalyzes the hydrolysis of internal (1->4)-alpha-D-glucosidic bonds, yielding a mixture of maltose, isomaltose, small amounts of glucose as well as small linear and branched oligosaccharides called dextrins (PubMed:12527308).
Pathways
