Abstract

We have recently revealed the structure of succinate dehydrogenase (complex II; or succinate: ubiquinone oxidoreductase, SQR) at 2.6 Angstrom. SQR is a functional member of both the Krebs cycle and the aerobic respiratory chain, thus an essential enzyme for any organisms, which perform oxygen respiration. Mutations of SQR cause tumours for human, premature aging for Caenorhabditis elegans and fungicide resistance for fungal pathogens. This proposal is to study the structures and functions of these mutants of mitochondrial SQRs using E. coli SQR system. E. coli SQR is an ideal model system to study these mutants since we can produce them in large quantity, which is essential for the biochemical and crystallographic studies. This proposal could reveal molecular mechanisms of these genetic disorders in human and the nematode and of fungicide resistance in fungal pathogens.
