AMY2A

Template:Short description Template:Cs1 config An Error has occurred retrieving Wikidata item for infobox Pancreatic alpha-amylase is an enzyme that in humans is encoded by the AMY2A gene.

Amylases are secreted proteins that hydrolyze 1,4-alpha-glucoside bonds in oligosaccharides and polysaccharides, and thus catalyze the first step in digestion of dietary starch and glycogen. The human genome has a cluster of several amylase genes that are expressed at high levels in either salivary gland or pancreas. This gene encodes an amylase isoenzyme produced by the pancreas.
