Effects of vitamin B supply on cellular processes of the facultative vitamin B consumer .

Vitamin B (cobalamin, herein B) is a key cofactor for most organisms being involved in essential metabolic processes. In microbial communities, B is often scarce, largely because only few prokaryotes can synthesize B and are thus considered B-prototrophs. B-auxotrophy is mostly manifested by the absence of the B-independent methionine synthase, MetE.

Department of Clinical Dietetics, Medical University of Warsaw, Erazma Ciolka 27 Street, Warsaw, 01-445, Poland.
Background: Kidney transplantation (kTx) is by far the most effective method of treating end-stage renal disease, with immunosuppressive therapy being obligatory for all, except identical twins. Despite kTx being the most effective treatment for end-stage renal disease, the patients face significant morbidity. They are often burdened with diabetes, anaemia, lipid disorders, all of which pose heightened risks for cardiovascular disease.

Musculoskeletal Care
March 2025
Jordan University Hospital, School of Medicine, University of Jordan, Amman, Jordan.
Background: Fibromyalgia-one of the chronic pain syndromes-characterised by pain, fatigue, and tenderness. The role of certain micronutrients like vitamin D, vitamin B12, and ferritin has been previously investigated in many primary studies aiming to assess both their therapeutic and diagnostic potential in the management of fibromyalgia.
Aim: To compare the levels of vitamin D, ferritin, and vitamin B12 between fibromyalgia patients and healthy controls.
Lettuce fortification through vitamin B-producing bacteria - proof of concept study.
J Sci Food Agric
January 2025
Center for Health & Bioresources, Bioresources Unit, AIT Austrian Institute of Technology, Tulln, Austria.
Background: Vitamin B (cobalamin) can be produced de novo only by certain bacteria and archaea. It plays a crucial role in the health of animals and humans, which obtain it only through diet, mainly from animal products. This study aimed to identify endophytic bacterial strains capable of synthesizing vitamin B and enriching edible plants with it as a potential solution for vitamin B deficiency in vegetarians, vegans, and people with poor diets.

Institute of Physiological Chemistry and Pathobiochemistry, University of Münster, Waldeyerstraße 15, 48149, Münster, Germany.
Light-responsive hydrogels are highly valued for their dynamic mechanical properties and biocompatibility. In this study, we present a hydrogel system that can either soften or strengthen on green light exposure, or remain unresponsive to light, depending on the addition of adenosyl cobalamin (AdoCbl) and Co. These protein-based hydrogels were formed using genetically encoded SpyTag-SpyCatcher chemistry and included green light-sensitive CarH protein domains.
