General rule information [?]

Accession PRU01211
Dates 5-JUN-2018 (Created)
22-NOV-2019 (Last updated, Version 2)
Data class Domain
Predictors PROSITE; PS51864; ASTACIN
Names Astacin-like domain; Peptidase family M12A domain
Function Astacin or M12A family zinc metalloproteases are found in bacteria and animals. They belong to the metzincin protease family and are synthesized as inactive precursors. The zinc atom in these enzymes acts as an electrophilic center to enhance the reactivity of a water molecule prior to nucleophilic attack on the carbonyl carbon of the scissile peptide bond.
