Improvement of the Thermal Stability of a Calcium-free, Alkaline α-Amylase by Site-directed Mutagenesis
Bacillus alkaliphile α-amylase thermostability site-directed mutagenesis
2008/4/20
Alkaline α-amylase from Bacillus sp. strain KSM-K38 (AmyK38) is a calcium-free enzyme that is stable against chelating and oxidative reagents. Recently, the thermostability of this enzyme was improved...
Creation of a Novel Hydrolase by Site-directed Mutagenesis of Malto-oligosyltrehalose Synthase
trehalose malto-oligosyltrehalose synthase site-directed mutagenesis transglycosylation hydrolysis
2008/4/20
Malto-oligosyltrehalose synthase (EC 5.4.99.15, MTSase) catalyzes the conversion of α-1,4-glucan to glycosyltrehalose by forming an α,α-1,1-glucosidic linkage on the reducing side of the α-1,4-glucan....
Site-Directed Mutagenesis of Tryptophan 622 of Thermoactinomyces vulgaris R-47 Glucoamylase:pH Optima and Activities of Five Mutants
glucoamylase optimal pH catalytic base
2008/4/20
In Aspergillus awamori glucoamylase, the optimal pH has been reported to increase to maintain activity by a mutation of Ser411 which forms a hydrogen-bond with a catalytic base (Fang and Ford, Protein...
