10504238-3	1999	Free dimethylbenzimidazole axial base-on cob(II)alamin was formed by photolysis of the corresponding adenosylcobalamin and cryotrapped in glycerol-aqueous glass.	5,6-dimethylbenzimidazole	5-26	metabolism of cobalamin associated B	Homo sapiens	41-44	
33797888-7	2021	In addition, they have revealed the practical utility of the dimethylbenzimidazole tail, an appendage unique to cobalamins and absent in the structural cousins, porphyrin, chlorin, and corphin, as an instrument for facilitating cofactor transfer between active sites.In this Account, we navigate the chemistry of the B12 trafficking pathway from its point of entry into cells, through lysosomes, and into the cytoplasm, where incoming cobalamin derivatives with a diversity of upper ligands are denuded by the beta-ligand transferase activity of CblC to the common cob(II)alamin intermediate.	5,6-dimethylbenzimidazole	61-82	metabolism of cobalamin associated B	Homo sapiens	112-115	
14661978-5	2003	These measurements can be used to estimate the influence of the dimethylbenzimidazole ligand on both the thermodynamics and kinetics of methyl transfer between methyltetrahydrofolate and cob(I)alamin or cob(I)inamide.	5,6-dimethylbenzimidazole	64-85	metabolism of cobalamin associated B	Homo sapiens	187-190

10504238-8	1999	The results identify the coenzyme"s on-board dimethylbenzimidazole moiety as the alpha-axial ligand to cob(II)alamin in ethanolamine deaminase in the substrate radical-Co(II) biradical catalytic intermediate state.	5,6-dimethylbenzimidazole	45-66	metabolism of cobalamin associated B	Homo sapiens	103-106	
10504238-11	1999	A 14% increase in the isotropic hyperfine coupling of the remote dimethylbenzimidazole (14)N nucleus in enzyme-bound versus free base-on cob(II)alamin shows an enhanced delocalization of unpaired spin density from Co(II) onto the axial ligand, which would contribute to the acceleration of the cobalt-carbon bond cleavage rate in situ.	5,6-dimethylbenzimidazole	65-86	metabolism of cobalamin associated B	Homo sapiens	137-140
