ENZYME entry: EC

Accepted Name
Protein N-terminal asparagine amidohydrolase.
Reaction catalysed
N-terminal L-asparaginyl-[protein] + H(2)O <=> N-terminal L-aspartyl-[protein] + NH(3)
  • This enzyme participates in the eukaryotic ubiquitin-dependent Arg/N-end rule pathway of protein degradation, promoting the turnover of intracellular proteins that initiate with Met-Asn.
  • Following the acetylation and removal of the initiator methionine, the exposed N-terminal asparagine is deaminated, resulting in its conversion to L-aspartate.
  • The latter serves as a substrate for EC making the protein susceptible to arginylation, polyubiquitination and degradation as specified by the N-end rule.
