A Amylase (also written as Alpha Amylase or α-Amylase) is a hydrolytic enzyme with CAS number 9000-85-5. This essential enzyme catalyzes the hydrolysis of starch by breaking internal α-1,4-glycosidic bonds, producing dextrins, maltose, and glucose. As one of the most commercially significant enzymes worldwide, A Amylase plays a crucial role in numerous industrial applications.

What is A Amylase?

A Amylase (EC 3.2.1.1, CAS 9000-85-5) is a hydrolytic enzyme that belongs to the amylase family. Unlike beta-amylase, which cleaves from the non-reducing end of starch chains, A Amylase randomly attacks internal α-1,4-glycosidic bonds, making it highly effective for starch liquefaction and saccharification processes.

This calcium-dependent metalloenzyme requires calcium ions (Ca²⁺) for structural stability and catalytic activity. It can be sourced from various origins including bacteria (particularly Bacillus species), fungi (Aspergillus niger), pancreatic sources, and through recombinant DNA technology.
