Emerging Role of Ferroptosis in Diabetes and Associated Complications: When Metabolic Dysregulation Meets Cell Death

Cell Proliferation, EarlyView.
This study identifies ferroptosis as a key driver of diabetes and its complications via iron metabolism and lipid peroxidation, elucidates organelle interactions underlying cell vulnerability, and provides insights for targeted therapies against metabolic disorders.

Divergent evolution of protein conformational dynamics in dihydrofolate reductase. [PDF]

, 2013
Molecular evolution is driven by mutations, which may affect the fitness of an organism and are then subject to natural selection or genetic drift. Analysis of primary protein sequences and tertiary structures has yielded valuable insights into the ...

Characterisation of a cold‐adapted, thermostable glucokinase from psychrophilic Pseudoalteromonas sp. AS‐131 reveals how the enzyme achieves high thermal stability without loss of cold adaptation

The FEBS Journal, EarlyView.
We investigated glucokinase from the psychrophilic Pseudoalteromonas sp. AS‐131 (PsGK), which was isolated from the Antarctic Ocean. Biochemical studies revealed that PsGK is a cold‐adapted enzyme with high thermal stability, in contrast to general cold‐adapted enzymes, which have low thermal stability.

Identification of the NADP⁺ Structural Binding Site and Coenzyme Effect on the Fused G6PD::6PGL Protein from Giardia lamblia

Biomolecules, 2019
Giardia lambia is a flagellated protozoan parasite that lives in the small intestine and is the causal agent of giardiasis. It has been reported that G. lamblia exhibits glucose-6-phosphate dehydrogenase (G6PD), the first enzyme in the pentose phosphate ...

Binuclear Manganese(III) Complexes as Electron Donors in D1/D2/Cytochrome b559 Preparations Isolated from Spinach Photosystem II Membrane Fragments [PDF]

, 1994
The capability of different manganese complexes to act as PS II electron donors in D1/D2/ cytochrome b 559 complexes has been analyzed by measuring actinic light-induced absorption changes at 680 nm (650 nm) and 340 nm, reflecting the photoaccumulation ...

Phycocyanobilin biosynthesis in Galdieria sulphuraria requires isomerization of phycoerythrobilin synthesized by bilin reductases

The FEBS Journal, EarlyView.
The biosynthesis of bilins, tetrapyrroles essential for light harvesting and sensing, is performed by specific enzymes (FDBRs). In Galdieria sulphuraria, both phycobiliprotein types bind phycocyanobilin, despite lacking the canonical synthesizing gene PCYA. Instead, PEBA and PEBB are encoded, producing phycoerythrobilin, proposed to be later isomerized

Aluminium effects on pyridine nucleotide redox state in roots of Scots pine

Acta Societatis Botanicorum Poloniae, 2014
After prolonged (3-9 weeks) hydroponic treatment of Scots pine seedlings with different concentrations (0.5-4.0 mM) of Al (AI(N03)3), the levels of pyridine nucleotides were determined in root homogenates.

A new branch of mammalian vitamin B6 metabolism: AKR1C‐mediated conversion of pyridoxal to pyridoxine and 4‐pyridoxolactone

The FEBS Journal, EarlyView.
Pyridoxal 5′‐phosphate (PLP) homeostasis relies on salvage enzymes, yet key metabolic branches remain undefined. We identify AKR1C isozymes as previously undescribed contributors that convert pyridoxal into pyridoxine or 4‐pyridoxolactone through reductase and dehydrogenase activities.
