DmdA‐independent lag phase shortening in Phaeobacter inhibens bacteria under stress conditions

The FEBS Journal, EarlyView.
The lag phase is crucial for resuming bacterial growth and can be shortened by fueling the methionine cycle with methyl groups from DMSP or other methylated compounds. While DmdA is the primary DMSP demethylase in Phaeobacter inhibens, stress activates additional enzymes like Bmt. This enzymatic flexibility allows bacteria to exit the lag phase rapidly,

A New Facet of Vitamin B12: Gene Regulation by Cobalamin-Based Photoreceptors.

Annual Review of Biochemistry, 2017
Living organisms sense and respond to light, a crucial environmental factor, using photoreceptors, which rely on bound chromophores such as retinal, flavins, or linear tetrapyrroles for light sensing.

Unexpected high levels of Cobalamin (Vitamin B12): Numerous interferences are decreased by PEG treatment. [PDF]

, 2016
Cobalamin (Vitamin B12) deficiency is a common cause of anemia. High levels of serum cobalamin is mainly due to cobalamin supplementation. It has also been associated with hematological malignancies, liver or renal diseases.

Creatinine, diet, micronutrients, and arsenic methylation in West Bengal, India. [PDF]

, 2011
BackgroundIngested inorganic arsenic (InAs) is methylated to monomethylated (MMA) and dimethylated metabolites (DMA). Methylation may have an important role in arsenic toxicity, because the monomethylated trivalent metabolite [MMA(III)] is highly toxic ...

Controversies in NEN: An ENETS position statement on nutritional support in neuroendocrine neoplasms

Journal of Neuroendocrinology, EarlyView.
Abstract Neuroendocrine neoplasms (NEN) themselves and also their treatment may cause malnutrition, inducing changes in physiological behaviour and eventually leading to increased rates of morbidity and mortality. Malnutrition is a common, under‐recognised and under‐treated condition in patients with NEN, and there are limited data available on the ...
