When proteins within the body get tagged with a molecule called ubiquitin, they are essentially marked for destruction. But they can be saved; a deubiquitinase enzyme can remove the ubiquitin, keeping ...
Ubiquitin is a small protein consisting of 76 amino acids that binds to lysine residues of substrates, usually by a combination of three enzymes: a ubiquitin-activating enzyme (E1, two types), a ...
Ubiquitination is a crucial post-translational modification process where the small protein ubiquitin is attached to target proteins, marking them for degradation or altering their function. This ...
