Ginsentide-like Coffeetides Isolated from Coffee Waste Are Cell-Penetrating and Metal-Binding Microproteins

open access: yesMolecules, 2023
Coffee processing generates a huge amount of waste that contains many natural products. Here, we report the discovery of a panel of novel cell-penetrating and metal ion-binding microproteins designated coffeetide cC1a–c and cL1–6 from the husk of two ...

Phoresis and Enhanced Diffusion Compete in Enzyme Chemotaxis [PDF]

open access: yesNano Lett. 2018, 18, 4, 2711-2717, 2021
Chemotaxis of enzymes in response to gradients in the concentration of their substrate has been widely reported in recent experiments, but a basic understanding of the process is still lacking. Here, we develop a microscopic theory for chemotaxis, valid for enzymes and other small molecules.

Oncogenic BRCA1,2 Mutations in the Human Lineage—A By-Product of Sexual Selection?

open access: yesBiomedicines, 2023
In this review, we discuss the long-known problem of tissue-specific carcinogenesis in BRCA1 and BRCA2 mutation carriers: while the genes are expressed ubiquitously, increased cancer risk is observed mostly in the breast and ovaries, and to a much lesser

Determining a critical threshold for G6PD activity below which red blood cell response to oxidative stress is poor

open access: yesMalaria Journal, 2020
Background Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common enzyme disorder in the world. Its main function is to generate NADPH that is required for anti-oxidative pathway in the cells especially in red blood cells (RBC).

COPPER ENZYMES IN ISOLATED CHLOROPLASTS. POLYPHENOLOXIDASE IN BETA VULGARIS.

open access: yesPlant Physiology, 1949
The chloroplast, as the seat of chlorophyll pigments in plants, occupies a unique position in the economy of the green cell. In recent years there has been a renewed interest in the reactions and properties of chloroplasts as a result of the work of Hill

Visual detection of isothermal nucleic acid amplification using pH-sensitive dyes

open access: yesBioTechniques, 2015
Nucleic acid amplification is the basis for many molecular diagnostic assays. In these cases, the amplification product must be detected and analyzed, typically requiring extended workflow time, sophisticated equipment, or both.

Natural catalytic immunoglobulins hydrolyzing histones as a link between inflammation and humoral immunity in schizophrenia

open access: yesEuropean Psychiatry, 2021
Introduction Schizophrenia pathogenesis is known to be associated with chronic low-grade inflammation. Inflammation can be caused by extracellular histones that are released from cells due to apoptosis dysfunction.
