Abstract

Only microorganisms can biosynthesise vitamin B12. The synthesis of the highly decorated corrin ring proceeds via a series of complex steps. We have obtained diffraction quality crystals of two of the enzymes: Bacillus megatarium CbiF, a AdoMet dependent C-methyltransferase, and Salmonella typhimurium CbiK, the anaerobic cobalamin cobaltochelatase, and propose to elucidate their structure. In this collaborative program between UCL London and York, we further propose to investigate the structure- function relationships of CbiF and CbiK by mutagenesis and enzymology. In addition, we already have overexpressing clones and will screen for crystallisation conditions for other purified cobalamin biosynthetic enzymes. (Joint with grant B08486).
