Combination of methane-inhibitors and hydrogen-acceptors: effects on in vitro rumen fermentation
Italian Journal of Animal ScienceMethanogenesis inhibition in vivo is often associated with higher dihydrogen (H2) emission without an increase in production efficiency. The objectives of this in vitro study were to test the effects of the addition of iodoform (IOD; 0.007% w/w on DM ...

Causation of human ulcerative colitis: A lead from an animal model that mirrors human disease
JGH Open, 2019 Most models of experimental colitis do not replicate human ulcerative colitis and do not help in defining the causation of human ulcerative colitis. Inducing pantothenic acid deficiency in pigs produces an ideal model in terms of extent, histology, and ...

Structural and biochemical analysis of a B12 superbinder
FEBS Letters, EarlyView.BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Design and numerical analysis of a 3 kWe flameless microturbine combustor for hydrogen fuel [PDF]
, 2019 In this work, a new 3 kWe flameless combustor for hydrogen fuel is designed and analyzed using CFD simulation. The strategy of the design is to provide a large volumetric combustion for hydrogen fuel without significant rise of the temperature.

FEBS Letters, EarlyView.Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

FEBS Letters, EarlyView.Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

The Role of Hydrogen for Sulfurimonas denitrificans’ Metabolism
PLoS ONE, 2014 Sulfurimonas denitrificans was originally isolated from coastal marine sediments. It can grow with thiosulfate and nitrate or sulfide and oxygen. Recently sequencing of its genome revealed that it encodes periplasmic and cytoplasmic [NiFe]-hydrogenases but the role of hydrogen for its metabolism has remained unknown.

FEBS Letters, EarlyView.Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.
