The study also found that cysteine residues catalyse peptide synthesis in water by joining together short peptide fragments that the team had previously found in a study published in Nature last year.

There’s a new kind of crosslink in proteins. Instead of an S–S bridge connecting two cysteine residues, it consists of an N–O–S bridge between a lysine and a cysteine. (The “N” comes ...

These activities comprise proteases, oxidoreductases and metabolic enzymes that rely on cysteine residues for catalysis and regulation. Functional cysteine residues demonstrate heightened reactivity ...

This amino acid residue is nearly three times as abundant as cysteine in the body: an average of 32 lysines dot every protein. There is tremendous utility in being able to expand the covalent ...

In the latest study, the ORNL team pinpointed four core amino acids called cysteine residues in the HGF protein critical to the PAN domain’s function and studied their behavior in human cancer cell ...

We have recently contributed with novel insights in the metabolic reprogramming of cells by the post-translational modification of redox-sensitive cysteine residues during chronic ER stress (eLife ...

S-palmitoylation refers to the addition of the saturated 16-carbon fatty acid palmitate at a cysteine residue in protein to form a liable thioester bond. The S-palmitoylation modification alters ...
