THE X-RAY STRUCTURE OF A COBALAMIN BIOSYNTHETIC ENZYME, COBALT PRECORRIN-4 METHYLTRANSFERASE, CBIF
Overview
Biosynthesis of the corrin ring of vitamin B12 requires the action of six, S-adenosyl-L-methionine (AdoMet) dependent transmethylases, closely, related in sequence. The first X-ray structure of one of these, cobalt-precorrin-4 transmethylase, CbiF, from Bacillus megaterium has been, determined to a resolution of 2.4 A. CbiF contains two alphabeta domains, forming a trough in which S-adenosyl-L-homocysteine (AdoHcy) binds. The, location of AdoHcy and a number of conserved residues, helps define the, precorrin binding site. A second crystal form determined at 3.1 A, resolution highlights the flexibility of two loops around this site. CbiF, employs a unique mode of AdoHcy binding and represents a new class of, transmethylase.
