| Type: | Domain | Name: | Peptidase S26A, all-beta subdomain |
| Description: | This entry represents an all-beta-sheet subdomain found in members of the peptidase S26A family of type 1 signal peptidase [, ]. The S26 family includes Escherichia colisignal peptidase, SPase, which is a membrane-bound endopeptidase with two N-terminal transmembrane segments and a C-terminal catalytic region []. SPase functions to release proteins that have been translocated into the inner membrane from the cell interior, by cleaving off their signal peptides. In SPase proteins, this domain is inserted into a domain with a complex fold made of several coiled beta-sheets that form a beta-ribbon structure and contains an SH3-like beta-barrel.Note: This signature only covers the all-beta subdomain, and not the beta-ribbon domain () it is inserted into. | Short Name: | Peptidase_S26A_all-beta_subdom |
