Abstract:
3-isopropylmalate dehydrogenase (3IPMDH) is the third enzyme in leucine biosynthesis and a promising target for the development of broad-spectrum antibacterial agents. We report here the expression, purification and biochemical characterisation of Haemophilus influenzae 3-isopropylmalate dehydrogenase. The observed enzyme inhibition by the reaction product NADH could represent a regulatory mechanism for 3IPMDH.
