An Alpha-Amylase is an enzyme that can catalyse the endohydrolysis of 1,4-Alpha-Glycosidic linkages in starch, glycogen, and related polysaccharides and oligosaccharides containing 3 or more 1,4-Alpha-Linked d-Dlucose units
- Context:
- It cuts Alpha-Bonds of Large Sugar Molecules.
- Example(s):
- Xanthomonas campestris pv. campestris http://www.uniprot.org/uniprot/Q4V0E4
- PMID 1313415: “Nonpathogenic mutants of Xanthomonas campestris pv. campestris, generated from transposon mutagenesis, accumulated extracellular polygalacturonate lyase, alpha-amylase, and endoglucanase in the periplasm”

- α-Amylase is the major form of amylase found in humans and other mammals. It is also an enzyme present in seeds which reserves are made of starch, or in fungi (baking yeast for instance). The enzyme cuts alpha-bonds of large sugar molecules.
