Structural characterization of novel cobalt corrinoids synthesized by enzymes of the vitamin B12 anaerobic pathway.
Santander P.J., Kajiwara Y., Williams H.J., Scott A.I.
Investigation on the use of the oxidized form (factor 3 (3a)) of the trimethylated intermediate (precorrin 3 (2)) as a substrate for the enzymes of the anaerobic pathway to vitamin B12 led to the synthesis of three pairs of novel cobalt corrinoids. The products were made with the aid of the Salmon ... >> More
Investigation on the use of the oxidized form (factor 3 (3a)) of the trimethylated intermediate (precorrin 3 (2)) as a substrate for the enzymes of the anaerobic pathway to vitamin B12 led to the synthesis of three pairs of novel cobalt corrinoids. The products were made with the aid of the Salmonella typhimurium enzymes CbiH, CbiF, CbiG, and CbiT, were synthesized in several 13C labeled versions, and were isolated as methylesters after esterification. Structures were determined by detailed NMR and MS analyses. Each set of products was obtained in the decarboxylated (RMe) and non-decarboxylated (R=CH2COOCH3) forms (at the C-12 position of the porphyrinoid). << Less

Biosynthesis of vitamin B12: factor IV, a new intermediate in the anaerobic pathway.
Scott A.I., Stolowich N.J., Wang J., Gawatz O., Fridrich E., Muller G.
The structure of a novel tetradehydrocorrin, factor IV, isolated from Propionibacterium shermanii has been established by multidimensional NMR spectroscopy. Incorporation of radiolabeled factor IV into cobyrinic acid established the biointermediacy of this cobalt complex, whose structure has impli ... >> More
The structure of a novel tetradehydrocorrin, factor IV, isolated from Propionibacterium shermanii has been established by multidimensional NMR spectroscopy. Incorporation of radiolabeled factor IV into cobyrinic acid established the biointermediacy of this cobalt complex, whose structure has implications for the mechanisms of the anaerobic pathway to B12. << Less
