Cobalamin and its binding protein in rat milk

, 1989
Cobalamin and its binding protein, haptocorrin, are present in rat milk throughout the lactation period. The concentration of cobalamin is approximately 0.3-times the concentration of the unsaturated binding protein.

Cobalamin and iron deficiency still presents a challenge in hereditary hemorrhagic telangiectasia

Scientific Reports
Hereditary hemorrhagic telangiectasia (HHT) leads to fragile blood vessels, causing frequent bleeding and anemia. Treatment mainly addresses iron levels and substitution. Although cobalamin (vitamin B12) is routinely tested in chronic anemia, its role in

Impaired lysosomal cobalamin transport in Alzheimer's disease

, 2015
Cobalamin (vitamin B12) is required for erythrocyte formation and DNA synthesis and it plays a crucial role in maintaining neurological function. As a coenzyme for methionine synthase and methylmalonyl-CoA mutase, cobalamin utilization depends on its ...

KINETICS OF COBALAMIN REPRESSION OF THE COB OPERON IN SALMONELLA-TYPHIMURIUM

, 1995
The cob operon in Salmonella typhimurium encodes 25 proteins involved in the biosynthesis of cobalamin. Expression of the cob operon is negatively feedback regulated by cobalamin via a translational control mechanism.
