Function

function

Ubiquitin ligase protein which is a component of the N-end rule pathway. Recognizes and binds to proteins bearing specific N-terminal residues that are destabilizing according to the N-end rule, leading to their ubiquitination and subsequent degradation.

Catalytic activity

  • S-ubiquitinyl-[E2 ubiquitin-conjugating enzyme]-L-cysteine + [acceptor protein]-L-lysine = [E2 ubiquitin-conjugating enzyme]-L-cysteine + N6-ubiquitinyl-[acceptor protein]-L-lysine.
    EC:2.3.2.27 (UniProtKB | ENZYME | Rhea)

Pathway

Protein modification; protein ubiquitination.
