Inhibition of cobalamin-dependent enzymes by cobalamin analogues in rats. [PDF]
Journal of Clinical Investigation, 1991 To determine which parts of the cobalamin (cbl) molecule are required for enzyme activity and which parts, if altered, might inhibit cbl-dependent enzyme activity, we synthesized 16 cbl analogues and administered them to nutritionally normal rats. The cbl analogues, with either modifications of the propionamide side chains of the A-, B-, and C-rings ...
