| Abstract: | Microbial dehydrogenase, such as leucine dehydrogenase （LDH）, has great advantages in the synthesis of optical amino acid and its derivatives by asymmetrical reductions of carbonyl compounds. This review covers the lat- est development of LDH from various sources, studies of its biochemical property, substrate specificity, kinetics of enzyme-catalyzed reactions as well as construction of engineering bacteria. Furthermore, its industrial application is discussed from the aspects of cofactor regeneration strategy and enzyme-membrane reactor and future development is also illustrated. |
