8652590-3	1996	The lower axial ligand to the cobalt in free methylcobalamin is the dimethylbenzimidazole nucleotide substituent of the corrin ring; when methylcobalamin binds to methionine synthase, the ligand is replaced by histidine 759, which in turn is linked by hydrogen bonds to aspartate 757 and thence to serine 810.	corrin	120-126	5-methyltetrahydrofolate-homocysteine methyltransferase	Homo sapiens	163-182	
1744096-7	1991	Studies with 14 different Cbl analogues with alterations in various portions of the corrin ring and the nucleotide showed that all of the analogues were able to fully activate human methionine synthase when they were reduced with 2-mercaptoethanol.	corrin	84-90	5-methyltetrahydrofolate-homocysteine methyltransferase	Homo sapiens	182-201
