Gamma-amylase

'Definition

noun, plural: gamma-amylases

A form of amylase that cleaves the last alpha-1,4-glycosidic linkages at the nonreducing end of amylase and amylopectin to yield glucose. It also cleaves the alpha-1-6-glycosidic linkages.


Supplement

Compared to alpha- and beta-amylases, the γ-amylase is most efficient in acidic environments (optimum pH of 3).


"Synonyms:

  • Glucan 1,4-α-glucosidase
  • amyloglucosidase
  • Exo-1,4-α-glucosidase
  • glucoamylase
  • lysosomal α-glucosidase
  • 1,4-α-D-glucan glucohydrolase

Compare: alpha-amylase, beta-amylase
