Novel Pathway for Corrinoid Compounds Production in Lactobacillus [PDF]
Frontiers in Microbiology, 2018 Vitamin B12 or cobalamin is an essential metabolite for humans, which makes it an interesting compound for many research groups that focus in different producer-strains synthesis pathways.

Nutrient sharing in the microbial world [PDF]
Frontiers in Microbiology, 2014 The stability and function of a microbial community depends on nutritional interactions among community members such as the cross-feeding of essential small molecules synthesized by a subset of the population.

Human gut Bacteroides capture vitamin B12 via cell surface-exposed lipoproteins [PDF]
eLife, 2018 Human gut Bacteroides use surface-exposed lipoproteins to bind and metabolize complex polysaccharides. Although vitamins and other nutrients are also essential for commensal fitness, much less is known about how commensal bacteria compete with each other

Evidence for corrin biosynthesis in the last universal common ancestor. [PDF]
FEBS JCobalamin biosynthesis can be traced back to the last universal common ancestor. After a stage of chemical evolution of the acetyl‐CoA pathway, the enzymatic synthesis of cobalamin evolved, allowing life to be independent of the insoluble solid‐state catalysts that tethered primordial CO2 assimilation to the Earth's crust, suggesting a role for corrin ...

The prospects for the use of vitamin B12 derivatives in pharmacology
Фармакоэкономика, 2023 Background. The structure of corrin tetrapyrrole macrocycles (compounds similar in structure to vitamin B12) is a kind of universal chemical template for targeted drug delivery, and the development of chemical sensors and antidotes.Objective ...

Identification of specific corrinoids reveals corrinoid modification in dechlorinating microbial communities [PDF]
Environmental Microbiology, 2014 Summary Cobalamin and other corrinoids are essential cofactors for many organisms. The majority of microbes with corrinoid‐dependent enzymes do not produce corrinoids de novo , and instead must acquire corrinoids produced by other organisms in their environment. However, the

Characterization of Vitamin B12 Compounds in Fermented Poultry Manure Fertilizers
Agriculture, 2021 (1) Background: Currently, no data are available on the vitamin B12 content of an organic fertilizer product, viz. fermented poultry manure, or whether the organic fertilizer product contains vitamin B12 or inactive corrinoids (or both).
