Literature-Based Summary (Non-Clinical Context)

Cobalamin-Dependent Enzymatic Activity

Vitamin B-12 (cobalamin) has been extensively studied in biochemical and cell-based models for its role as a cofactor in key enzymatic reactions, including methionine synthase and methylmalonyl-CoA mutase. These pathways are central to methylation processes, nucleotide synthesis, and cellular energy metabolism.
