An Oxidation Stable and Chelator-resistant, Calcium-free α-Amylase from the Alkaliphilic Bacillus Isolate KSM-K38
calcium-free α-amylase Bacillus oxidative stability chelator resistance
2008/4/20
We found a novel α-amylase (AmyK38) in a culture of a novel, alkaliphilic Bacillus sp. strain KSM-K38. The enzyme was an alkaline, liquefying α-amylase, having a pH optimum of 8.0-9.5, and exhibiting ...
Molecular Modeling and Implications of a Bacillus α-Amylase that Acquires Enhanced Thermostability and Chelator Resistance by Deletion of an Arginine-glycine Residue
α-amylase homology modeling molecular dynamics simulation thermostability chelator resistance

Resistance to chelators, as well as thermostability, of an alkaline α-amylase (AmyK, formerly named LAMY) from an alkaliphilic Bacillus sp. strain was significantly improved by deletion of Arg181-Gly1...
Cyclization Reaction Catalyzed by Bacillus cereus Branching Enzyme, and the Structure of Cyclic Glucan Produced by the Enzyme from Amylose
