| Type: | Domain | Name: | PA domain |
| Description: | The PA (Protease associated) domain is found as an insert domain in diverse proteases, which include the MEROPS peptidase families A22B, M28, and S8A []. The PA domain is also found in a plant vacuolar sorting receptor and members of the RZF family, e.g. . It has been suggested that this domain forms a lid-like structure that covers the active site in active proteases, and is involved in protein recognition in vacuolar sorting receptors []. | Short Name: | PA_domain |
