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

Purification and characterization of cobyrinic acid a,c-diamide synthase from Pseudomonas denitrificans.
Debussche L., Thibaut D., Cameron B., Crouzet J., Blanche F.
Cobyrinic acid a,c-diamide synthase, which catalyzes the conversion of cobyrinic acid to cobyrinic acid a,c-diamide via the intermediate formation of cobyrinic acid c-monoamide, was purified 155-fold to homogeneity from extracts of a recombinant strain of Pseudomonas denitrificans by high-performa ... >> More
Cobyrinic acid a,c-diamide synthase, which catalyzes the conversion of cobyrinic acid to cobyrinic acid a,c-diamide via the intermediate formation of cobyrinic acid c-monoamide, was purified 155-fold to homogeneity from extracts of a recombinant strain of Pseudomonas denitrificans by high-performance liquid chromatography. The enzyme has an apparent molecular weight of 86,000 and consists of two identical subunits of Mr 45,000, as estimated by gel electrophoresis under denaturing conditions. Stepwise Edman degradation provided the N-terminal sequence of the first 15 amino acids. Glutamine was shown to be the preferred amino group donor (Km = 20.3 microM), but it could be replaced by ammonia (Km = 12 mM). The reaction was ATP dependent and exhibited a broad optimum pH around 7.3. Km values for (CN,aq)cobyrinic acid, (aq)2cobyrinic acid, and (CN,aq)cobyrinic acid c-monoamide were 160, greater than or equal to 250, and 71 microM, respectively. Hydrogenobyrinic acid and hydrogenobyrinic acid c-monoamide were shown to be much better substrates, with Km values of 0.41 and 0.21 microM, respectively. << Less
