Multiple Disulfide-Bonded States of Native Proteins: Estimate of Number Using Probabilities of Disulfide Bond Formation

open access: yesMolecules, 2020
The polypeptide backbone of proteins is held together by two main types of covalent bonds: the peptide bonds that link the amino acid residues and the disulfide bonds that link pairs of cysteine amino acids. Disulfide bonds form as a protein folds in the

p53 Suppresses Metabolic Stress-Induced Ferroptosis in Cancer Cells

open access: yesCell Reports, 2018
How cancer cells respond to nutrient deprivation remains poorly understood. In certain cancer cells, deprivation of cystine induces a non-apoptotic, iron-dependent form of cell death termed ferroptosis.

Low‐Level Arsenic Removal from Drinking Water

open access: yesGlobal Challenges, 2019
The reported ability of cysteine and cystine to bind typical arsenic oxy‐ions in water is used as a basis for a study of the potential for using a surfactant with a cysteine head‐group for selective arsenic binding and removal in an ion flotation process.

The Mechanism and Regulation of Disulfidptosis and Its Role in Disease

open access: yesBiomedicines
Disulfidptosis is a recently identified form of regulatory cell death (RCD), Which has emerged as a research hotspot due to its distinctive feature of accumulating protein disulfide bonds, setting it apart from other RCD mechanisms.

The effect of amino acid enantiomers on activity of selected enzymes in soil

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2011
This work was aimed to test the effect of selected amino acid enantiomers on activity of casein-protease and acid phosphomonoesterase in soil. Casein-protease was selected due to its key role in nitrogen mineralization and acid phosphomonoesterase due to
