Journal of Experimental Medicine, 1999 In studying the subdominant status of two cysteine-containing influenza virus nuclear protein (NP) determinants (NP39–47 and NP218–226) restricted by H-2Kd, we found that the antigenicity of synthetic peptides was enhanced 10–100-fold by treatment with ...

Understanding the role of cysteine in ferroptosis: progress & paradoxes
The FEBS Journal, 2021 Cysteine is a conditionally essential amino acid required for the synthesis of proteins and many important intracellular metabolites. Cysteine depletion can trigger iron‐dependent nonapoptotic cell death–ferroptosis.

Molecules, 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

Cysteine metabolic circuitries: druggable targets in cancer
British Journal of Cancer, 2020 To enable survival in adverse conditions, cancer cells undergo global metabolic adaptations. The amino acid cysteine actively contributes to cancer metabolic remodelling on three different levels: first, in its free form, in redox control, as a component

The Potential of a Protein Model Synthesized Absent of Methionine
Molecules, 2022 Methionine is an amino acid long thought to be essential, but only in the case of protein synthesis initiation. In more recent years, methionine has been found to play an important role in antioxidant defense, stability, and modulation of cell and ...

Cysteine Toxicity Drives Age-Related Mitochondrial Decline by Altering Iron Homeostasis.
Cell, 2020 Mitochondria and lysosomes are functionally linked, and their interdependent decline is a hallmark of aging and disease. Despite the long-standing connection between these organelles, the function(s) of lysosomes required to sustain mitochondrial health ...
