Cobalamin Related Parameters and Disease Patterns in Patients With Increased Serum Cobalamin Levels [PDF]

open access: yesPLoS ONE, 2012
BACKGROUND:Measurement of serum cobalamin levels is routinely used to diagnose cobalamin deficiency. Surprisingly, approximately 15% of patients have high cobalamin levels and no consensus exists regarding the clinical implications.

The cobalamin-binding protein in zebrafish is an intermediate between the three cobalamin-binding proteins in human. [PDF]

open access: yesPLoS ONE, 2012
In humans, three soluble extracellular cobalamin-binding proteins; transcobalamin (TC), intrinsic factor (IF), and haptocorrin (HC), are involved in the uptake and transport of cobalamin.

Gene identification for the cblD defect of vitamin B12 metabolism [PDF]

open access: yes, 2008
Background Vitamin B12 (cobalamin) is an essential cofactor in several metabolic pathways. Intracellular conversion of cobalamin to its two coenzymes, adenosylcobalamin in mitochondria and methylcobalamin in the cytoplasm, is necessary for the ...

A study into the cobalamin-dependent methionine synthase reactivation mechanism in corynebacterium glutamicum [PDF]

open access: yes, 2009
PhDMethionine is one of the seven essential amino-acids for humans and is also used in feed supplements, predominantly for poultry and felines. Thus there is commercial interest in producing this nutrient. The final step in the biological synthesis of

Interspecies transfer of biosynthetic cobalamin for complete dechlorination of trichloroethene by Dehalococcoides mccartyi

open access: yesWater Science and Technology, 2022
Complete dechlorination of trichloroethene (TCE) by Dehalococcoides mccartyi is catalyzed by reductive dehalogenases (RDases), which possess cobalamin as the crucial cofactor. However, virtually all D. mccartyi isolated thus far are corrinoid auxotrophs.

Enhanced cobalamin biosynthesis in Ensifer adhaerens by regulation of key genes with gradient promoters

open access: yesSynthetic and Systems Biotechnology, 2022
Cobalamin is an essential human vitamin widely used in the pharmaceutical, food, and feed additive industries and currently produced by bacteria or archaea. Ensifer adhaerens HY-1 is an industrial strain that also produces cobalamin.

De Novo Cobalamin Biosynthesis, Transport, and Assimilation and Cobalamin-Mediated Regulation of Methionine Biosynthesis in Mycobacterium smegmatis. [PDF]

open access: yes, 2021
Cobalamin is an essential cofactor in all domains of life, yet its biosynthesis is restricted to some bacteria and archaea. Mycobacterium smegmatis, an environmental saprophyte frequently used as surrogate for the obligate human pathogen M. tuberculosis,

The Intestinal Microbiome in Dogs with Chronic Enteropathies and Cobalamin Deficiency or Normocobalaminemia—A Comparative Study

open access: yesAnimals, 2023
Cobalamin deficiency is a common sequela of chronic enteropathies (CE) in dogs. Studies comparing the intestinal microbiome of CE dogs with cobalamin deficiency to those that are normocobalaminemic are lacking.
