A hidden cause of infertility in hypothyroid patients [PDF]

open access: yes, 2020
Methylene tetrahydrofolate reductase (MTHFR) gene mutations could be the cause of infertility in hypothyroid patients. Hence, it is worthy to screen for MTHFR gene mutations in infertile hypothyroid females and their partners if infertility persists ...

The flavoheme reductase Ncb5or protects cells against endoplasmic reticulum stress-induced lipotoxicity[S]

open access: yesJournal of Lipid Research, 2010
NCB5OR is a novel flavoheme reductase with a cytochrome b5-like domain at the N-terminus and a cytochrome b5 reductase-like domain at the C terminus. Ncb5or knock-out mice develop insulin deficient diabetes and loss of white adipose tissue.

Characterization of d-xylose reductase, XyrB, from Aspergillus niger

open access: yesBiotechnology Reports, 2021
d-xylose reductase is a member of the aldo-keto reductase family, and is involved in d-xylose and l-arabinose conversion through the Pentose Catabolic Pathway (PCP) in fungi.

Protein folding causes an arrest of preprotein translocation into mitochondria in vivo [PDF]

open access: yes, 1991
With vital yeast cells, a hybrid protein consisting of the amino- terminal third of the precursor to cytochrome b2 and of the entire dihydrofolate reductase was arrested on the import pathway into mitochondria.

Production, characterization and determination of the real catalytic properties of the putative "succinate dehydrogenase" from Wolinella succinogenes [PDF]

open access: yes, 2009
Both the genomes of the epsilonproteobacteria Wolinella succinogenes and Campylobacter jejuni contain operons (sdhABE) that encode for so far uncharacterized enzyme complexes annotated as ‘non-classical’ succinate:quinone reductases (SQRs).

The Plant Short-Chain Dehydrogenase (SDR) superfamily:genome-wide inventory and diversification patterns [PDF]

open access: yes, 2012
Background Short-chain dehydrogenases/reductases (SDRs) form one of the largest and oldest NAD(P)(H) dependent oxidoreductase families. Despite a conserved 'Rossmann-fold' structure, members of the SDR superfamily exhibit low sequence similarities, which

The newfound relationship between extrachromosomal DNAs and excised signal circles

open access: yesFEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Murburn concept: a paradigm shift in cellular metabolism and physiology

open access: yesBiomolecular Concepts, 2020
Two decades of evidence-based exploratory pursuits in heme-flavin enzymology led to the formulation of a new biological electron/moiety transfer paradigm, called murburn concept.

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Growth and Mineral Nutrition of the Chickpea ( Cicer arietinum L.)-Rhizobia Symbiosis under Water Deficit

open access: yesBrazilian Archives of Biology and Technology, 2018
The effect of the water deficit on the fresh and dry weight in the various parts of the plant and on several mineral processes in different symbiotic combinations for the chickpea (Cicer arietinum L.) varieties was studied.
