Vitamin B12, or cobalamin, is one of the most structurally complex small molecules made in Nature. Major progress has been made over the past decade in understanding how this synthesis is accomplished. This review covers some of the most important findings that have been made and provides the reader with a complete description of the transformation of uroporphyrinogen III into adenosylcobalamin (AdoCbl). 183 references are cited. << Less

Studies with cell-free protein preparations from a series of recombinant strains of Pseudomonas denitrificans demonstrated that precorrin-3 is converted into a further trimethylated intermediate, named precorrin-3B, along the pathway to coenzyme B12. It was then shown that the part of the pathway from precorrin-3 (called precorrin-3A hereafter) to precorrin-6x involves three intermediates, precorrin-3B, precorrin-4, and precorrin-5. Precorrin-3B was isolated in its native (reduced) as well as its oxidized (factor-IIIB) states, and precorrin-4 was isolated in its oxidized form only (factor-IV). Both factors were in vitro precursors of precorrin-6x. The synthesis of precorrin-6x from precorrin-3A was shown to be catalyzed by four enzymes, CobG, CobJ, CobM, and CobF, intervening in this order. They were purified to homogeneity. CobG, which converts precorrin-3A to precorrin-3B, was found to be an iron-sulfur protein responsible for the oxidation known to occur between precorrin-3A and precorrin-6x, and CobJ, CobM, and CobF are the C-17, C-11, and C-1 methylases, respectively. The acetate fragment is extruded after precorrin-4 formation. This study combined with our recent structural studies on factor-IV (D. Thibaut, L. Debussche, D. Fréchet, F. Herman, M. Vuilhorgne, and F. Blanche, J. Chem. Soc. Chem. Commun. 1993:513-515, 1993) and precorrin-3B (L. Debussche, D. Thibaut, M. Danzer, F. Debu, D. Fréchet, F. Herman, F. Blanche, and M. Vuilhorgne, J. Chem. Soc. Chem. Commun. 1993:1100-1103, 1993) provides a first step-by-step picture of the sequence of the enzymatic reactions leading to the corrin ring in P. denitrificans. << Less
