Abstract

Abstract: The L-lactate dehydrogenase of Bacillus stearothermophilus (BSLDH) is a thermostable enzyme with considerable potential for applications in asymmetric synthesis. An understanding of the factors controlling its structural specificity and stereospecificity is therefore of interest. In this paper the effects of Gln102-Arg and Cys97-Gly mutations have been evaluated. In a survey of thirteen 2-keto acids, the Q102R mutation was found to ...
