Vitamin B12 and Reproductive Health: Clinical Insights, Emerging Mechanistic Understanding, and Nutritional Aspects. [PDF]

open access: yesMol Reprod Dev
ABSTRACT Epidemiological data from assisted reproductive technologies (ART) link vitamin B12 (VitB12) deficiency to shorter gestation, low birth weight, and reduced live birth rates. VitB12 also plays a critical role in fertility for both sexes by supporting gamete quality.

Influence of corrinoid antagonists on methanogen metabolism [PDF]

open access: bronzeJournal of Bacteriology, 1981
Iodopropane inhibited cell growth and methane production when Methanobacterium thermoautotrophicum, Methanobacterium formicicum, and Methanosarcina barkeri were cultured on H2-CO2. Iodopropane (40 microM) inhibited methanogenesis (30%) and growth (80%) when M. barkeri was cultured mixotrophically on H2-CO2-methanol.

Versatility in Corrinoid Salvaging and Remodeling Pathways Supports Corrinoid-Dependent Metabolism in Dehalococcoides mccartyi [PDF]

open access: yesApplied and Environmental Microbiology, 2012
ABSTRACTCorrinoids are cobalt-containing molecules that function as enzyme cofactors in a wide variety of organisms but are produced solely by a subset of prokaryotes. Specific corrinoids are identified by the structure of their axial ligands. The lower axial ligand of a corrinoid can be a benzimidazole, purine, or phenolic compound. Though it is known

Influence of vitamin B12 and light on the formation of chlorosomes in green- and brown-colored Chlorobium species [PDF]

open access: yes, 1993
The specific Bchl a and c content of the vitamin B12-dependent Chlorobium limicola strain 1230 decreased strongly under vitamin B12 limitation. In comparison to a regularly grown culture (20 g vitamin B12/l) the specific Bchl c content of a B12-limited ...

Methylobacterium sp. 2A is a plant growth-promoting rhizobacteria that has the potential to improve potato crop yield under adverse conditions [PDF]

open access: yes, 2020
A Gram-negative pink-pigmented bacillus (named 2A) was isolated from Solanum tuberosum L. cv. Desirée plants that were strikingly more developed, presented increased root hair density, and higher biomass than other potato lines of the same age.

Incomplete Wood-Ljungdahl pathway facilitates one-carbon metabolism in organohalide-respiring Dehalococcoides mccartyi. [PDF]

open access: yes, 2014
The acetyl-CoA "Wood-Ljungdahl" pathway couples the folate-mediated one-carbon (C1) metabolism to either CO2 reduction or acetate oxidation via acetyl-CoA.

Mouse transcobalamin has features resembling both human transcobalamin and haptocorrin.

open access: yesPLoS ONE, 2011
In humans, the cobalamin (Cbl) -binding protein transcobalamin (TC) transports Cbl from the intestine and into all the cells of the body, whereas the glycoprotein haptocorrin (HC), which is present in both blood and exocrine secretions, is able to bind ...

Supplementing lactating dairy cows with a vitamin B12 precursor, 5,6-dimethylbenzimidazole, increases the apparent ruminal synthesis of vitamin B12

open access: yesAnimal, 2015
Cobalamin (CBL), the biologically active form of vitamin B12, and its analogs, are produced by bacteria only if cobalt supply is adequate. The analogs differ generally by the nucleotide moiety of the molecule.
