Cobalamin (Vitamin B12) Induced a Shift in Microbial Composition and Metabolic Activity in an in vitro Colon Simulation

Frontiers in Microbiology, 2018
Cobalamin deficiency is believed to be related to disturbances in cell division, neuropathy, nervous system disease and pernicious anemia. Elderly people are usually advised to supplement their diets with cobalamin.

Transcriptomic and proteomic changes associated with cobalamin-dependent propionate production by the rumen bacterium Xylanibacter ruminicola

mSystems
Xylanibacter ruminicola is an abundant rumen bacterium that produces propionate in a cobalamin (vitamin B12)-dependent manner via the succinate pathway.

Dynamics and interactions of cobalamin and folate status during advanced aging – a longitudinal study in a community-dwelling cohort with multiple follow-ups

Nutrition Journal, 2020
Background Older people are reported to be prone to imbalances between cobalamin and folate status with possible adverse effects on health. This longitudinal study investigates dynamics and interactions of cobalamin and folate status in a cohort of ...

Guidelines for diagnosis and management of the cobalamin-related remethylation disorders cblC, cblD, cblE, cblF, cblG, cblJ and MTHFR deficiency

Journal of Inherited Metabolic Disease, 2016
BackgroundRemethylation defects are rare inherited disorders in which impaired remethylation of homocysteine to methionine leads to accumulation of homocysteine and perturbation of numerous methylation reactions.ObjectiveTo summarise clinical and ...

Green‐Light‐Induced Inactivation of Receptor Signaling Using Cobalamin‐Binding Domains

Angewandte Chemie, 2017
Optogenetics and photopharmacology provide spatiotemporally precise control over protein interactions and protein function in cells and animals. Optogenetic methods that are sensitive to green light and can be used to break protein complexes are not ...

Fat digestibility is reduced in old cats with subnormal cobalamin concentrations

Journal of Nutritional Science, 2014
Fat digestibility is decreased in old cats for unknown reasons. Subclinical gastrointestinal diseases and pancreatic dysfunction, both related to ageing, can affect food digestibility.

Principles for Rigorous Design and Application of Synthetic Microbial Communities

Advanced Science, EarlyView.
SynComs are artificially designed to enable inter‐species metabolic interactions, metabolic division of labor, and ecological interactions that can elicit phenotypes like colonization stability and environmental adaptation. This systematic review explores the processes used to construct SynComs, the assessment of the mechanisms of metabolic interaction

Microbial metabolism: optimal control of uptake versus synthesis [PDF]

, 2014
Microbes require several complex organic molecules for growth. A species may obtain a required factor by taking up molecules released by other species or by synthesizing the molecule.
