A Detoxification Enzyme for Apis mellifera Newly Characterized by Recombinant Expression: 10-Formyl Tetrahydrofolate Dehydrogenase. [PDF]

Front Insect Sci, 2022
Honeybees are important managed pollinators that perform important ecological and economic functions. In recent decades, the obligate ectoparasite Varroa destructor severely affected survival of honeybees as it either feeds on hemolymph and fat bodies or acts as a vector for viruses.

Activated brown adipose tissue releases exosomes containing mitochondrial methylene tetrahydrofolate dehydrogenase (NADP dependent) 1-like protein (MTHFD1L). [PDF]

Biosci Rep, 2022
Abstract Brown adipose tissue (BAT) is a promising weapon to combat obesity and metabolic disease. BAT is thermogenic and consumes substantial amounts of glucose and fatty acids as fuel for thermogenesis and energy expenditure. To study BAT function in large human longitudinal cohorts, safe and precise detection methodologies are ...

The role of tetrahydrofolate dehydrogenase in the hepatic supply of tetrahydrobiopterin in rats [PDF]

Biochemical Journal, 1976
The reduction of 7,8-dihydrobiopterin to 5,6,7,8-tetrahydrobiopterin by rat liver tetrahydrofolate dehydrogenase (5,6,7,8-tetrahydrofolate-NADP+ oxidoreductase, EC 1.5.1.3) is competitively inhibited by trimethoprim lactate (apparent Ki 0.285 muM). An apparent Michaelis constant of 43 muM for dihydrobiopterin was obtained, which is 430 times higher ...

The crystal structure of a bacterial, bifunctional 5, 10 methylene‐tetrahydrofolate dehydrogenase/cyclohydrolase [PDF]

Protein Science, 1999
AbstractThe structure of a bifunctional 5, 10‐methylene‐tetrahydrofolate dehydrogenase/cyclohydrolase from Escherichia coli has been determined at 2.5 Å resolution in the absence of bound substrates and compared to the NADP‐bound structure of the homologous enzyme domains from a trifunctional human synthetase enzyme.

Non-canonical dihydrolipoyl transacetylase promotes chemotherapy resistance via mitochondrial tetrahydrofolate signaling [PDF]

Nature Communications
Chemotherapy is often a primary treatment for cancer. However, resistance leads to therapeutic failure. Acetylation dynamics play important regulatory roles in cancer cells, but the mechanisms by which acetylation mediates therapy resistance remain ...

Sorbitol Uptake and Oxygen Transfer Shape AOX1 Promoter Induction in Formate Dehydrogenase‐Deficient Komagataella phaffii [PDF]

Microbial Biotechnology
In Komagataella phaffii, the use of formate as an AOX1 promoter (PAOX1) inducer in combination with sorbitol, a non‐repressive carbon source, has emerged as a promising alternative to methanol‐based expression systems.

Methylene tetrahydrofolate dehydrogenase/cyclohydrolase and the synthesis of 10‐CHO‐THF are essential inLeishmania major [PDF]

Molecular Microbiology, 2009
Summary10‐Formyl tetrahydrofolate (10‐CHO‐THF) is a key metabolite in C1 carbon metabolism, arising through the action of formate‐tetrahydrofolate ligase (FTL) and/or 5,10‐methenyltetrahydrofolate cyclohydrolase/5,10‐methylene tetrahydrofolate dehydrogenase (DHCH).Leishmania majorpossesses singleDHCH1andFTLgenes encoding exclusively cytosolic proteins,

The effect of tetrahydrofolate on the reduction of electron transfer flavoprotein by sarcosine and dimethylglycine dehydrogenases [PDF]

Biochemical Journal, 1982
Pig liver electron transfer flavoprotein (ETF) is rapidly reduced by sarcosine and dimethylglycine dehydrogenases to the anionic semiquinone form, the subsequent formation of the flavoquinol form being a much slower process. In the presence of tetrahydrofolate the yield of anionic semiquinone at the end of the rapid phase of reduction of ETF is only ...

Amino acid metabolism of the thermophilic acetogen Thermacetogenium phaeum. [PDF]

PLoS ONE
Anaerobic microbial degradation of the amino acids glycine and serine either occurs through enzymes of the so-called Stickland reaction or alternatively through the glycine cleavage system (GCS).
