Opis ogólny

Vitamin B12 cobalamin refers to a group of chemically-related cobalt containing molecules. The physiologically active forms of vitamin B12 include methylcobalamin and adenosylcobalamin, whereas hydroxocobalamin (vitamin B12a, OHCbl) and cyanocobalamin (CNCbl) are storage and delivery forms.

Zastosowanie

Coenzyme B12 has been used as a supplement for culturing plasmid variants in in vivo assay of yvrC-lacZ fusions.

Działania biochem./fizjol.

Vitamin B12 cobalamin is involved in DNA synthesis and fatty acid synthesis. It also plays a vital role as a coenzyme in the conversion of mitochondrial methylmalonyl co-enzyme A to succinyl co-enzyme A.

Coenzyme B(12) has a key role in various enzymatic reactions and controls expression of bacterial genes through riboswitches. Here we report the crystal structure of the Symbiobacterium thermophilum B(12) riboswitch bound to its ligand adenosylcobalamin. The riboswitch forms a unique

This review examines deoxyadenosylcobalamin (Ado-B12) biosynthesis, transport, use, and uneven distribution among living forms. We describe how genetic analysis of enteric bacteria has contributed to these issues. Two pathways for corrin ring formation have been found-an aerobic pathway (in P.

Vitamin B(12) and its biologically active counterparts possess the only examples of carbon-cobalt bonds in living systems. The role of such motifs as radical reservoirs has potential application in future catalytic and electronic nanodevices. To fully understand radical generation in

Coenzyme B(12) can assist radical enzymes that accomplish the vicinal interchange of a hydrogen atom with a functional group. It has been proposed that the Co-C bond homolysis of coenzyme B(12) to cob(II)alamin and the 5'-deoxyadenosyl radical is aided by hydrogen bonding

We present here an energetic and atomistic description of how D-ornithine 4,5-aminomutase (OAM), an adenosylcobalamin (AdoCbl; coenzyme B(12))-dependent isomerase, employs a large-scale protein domain conformational change to orchestrate the homolytic rupture of the Co-C bond. Our results suggest that in
