Abstract

Formate dehydrogenase N (Fdh-N) and nitrate reductase (Nar) are the essential components of the nitrate respiration in E. coli under anaerobic conditions. We have already purified these two membrane proteins and have obtained good crystals of Fdh-N diffracting up to 1.6 Angstrom. This proposal is to solve the structures of these two enzymes. Fdh-N is one of the largest membrane proteins so far crystallised (trimer of 180kDa monomers). A very high resolution structure of the enzyme would provide essential information to study the architecture of membrane protein complexes. The structures of Fdh-N and Nar could also reveal a detailed proton translocation mechanism by these enzymes and how this interesting organism adapts to environmental change.
