This enzyme cleaves its substrate at 1,4 alpha linkages.
In humans, expression of this enzyme in one tissue is carried out from a promoter that is an unusual combination of a gamma actin pseudogene and a retrotransposon. Its activity can be tested using the Bernfeld assay and quantified in somogyi units. The thermostable taka variant of this enzyme comes from the koji fungus and the BamH1 restriction enzyme comes from a bacterium named for its production of this enzyme. Examples of this enzyme that are "liquefying" act internally on the substrate. Limit dextrins are a product of the (*) beta form of this enzyme. This enzyme cleaves its substrate at 1,4 alpha linkages. This enzyme is produced in the pancreas and can also be found in saliva. For 10 points, name this enzyme that degrades starch.
