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	mitochondrially encoded cytochrome c oxidase II	Homo sapiens	168-174	
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	mitochondrially encoded cytochrome c oxidase II	Homo sapiens	214-220	
9722671-7	1998	Upon suicide inactivation with a [15N2]imidazolyl analog, the octet signals due to Co(II) showed superhyperfine splitting into doublets, indicating axial coordination of 5,6-dimethylbenzimidazole to the cobalamin bound to diol dehydratase.	5,6-dimethylbenzimidazole	170-195	mitochondrially encoded cytochrome c oxidase II	Homo sapiens	83-89	
25839944-7	2015	Collectively, our results indicate that a reduction in the basicity of the lower axial ligand causes changes to the cofactor"s electronic structure in the Co(II) state that replicate the effects seen upon binding of Co(II)Cbl to Class I isomerases, which replace the lower axial dimethylbenzimidazole ligand of AdoCbl with a protein-derived histidine (His) residue.	5,6-dimethylbenzimidazole	279-300	mitochondrially encoded cytochrome c oxidase II	Homo sapiens	155-161
