Identifying and predicting the pathogenic effects of a novel variant inducing severe early onset MMA: a bioinformatics approach

Hereditas, 2023
Background Methylmalonic acidemia (MMA) is a rare metabolic disorder resulting from functional defects in methylmalonyl-CoA mutase. Mutations in the MMAB gene are responsible for the cblB type of vitamin B12-responsive MMA.

Influence of corrinoid antagonists on methanogen metabolism [PDF]

Journal of Bacteriology, 1981
Iodopropane inhibited cell growth and methane production when Methanobacterium thermoautotrophicum, Methanobacterium formicicum, and Methanosarcina barkeri were cultured on H2-CO2. Iodopropane (40 microM) inhibited methanogenesis (30%) and growth (80%) when M. barkeri was cultured mixotrophically on H2-CO2-methanol.

Sustainable Growth of Dehalococcoides mccartyi 195 by Corrinoid Salvaging and Remodeling in Defined Lactate-Fermenting Consortia [PDF]

, 2014
Corrinoids are essential cofactors of reductive dehalogenases in Dehalococcoides mccartyi, an important bacterium in bioremediation, yet sequenced D. mccartyi strains do not possess the complete pathway for de novo corrinoid biosynthesis.

Proteome adaptations of the organohalide-respiring Desulfitobacterium hafniense strain DCB-2 to various energy metabolisms

Frontiers in Microbiology, 2023
IntroductionDesulfitobacterium hafniense was isolated for its ability to use organohalogens as terminal electron acceptors via organohalide respiration (OHR). In contrast to obligate OHR bacteria, Desulfitobacterium spp.

Microbes display broad diversity in cobamide preferences

mSystems
Cobamides, the vitamin B12 (cobalamin) family of cofactors, are used by most organisms but produced by only a fraction of prokaryotes, and are thus considered key shared nutrients among microbes.

Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function

FEBS Open Bio, Volume 16, Issue 8, Page 1537-1549, August 2026.
We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...

Functional Expression and Characterization of a Panel of Cobalt and Iron-Dependent Nitrile Hydratases

Molecules, 2020
Nitrile hydratases (NHase) catalyze the hydration of nitriles to the corresponding amides. We report on the heterologous expression of various nitrile hydratases.

Methanol Metabolism in the Cytochrome and Menaquinone‐Containing Acetogen Moorella thermoacetica

Environmental Microbiology, Volume 28, Issue 7, July 2026.
The thermophilic acetogenic bacterium Moorella thermoacetica is a promising platform organism to convert C1 compounds to valuable products. Gaseous C1 substrates are technically difficult to use for fermentation in an industrial scale, but methanol, which can be produced chemically from carbon dioxide, is a suitable alternative.
