| Accession | GenProp0205 |
| Name | signal recognition system, bacterial |
| Type | SYSTEM |
| Description | The signal recognition system in bacteria includes the signal recognition particle (SRP) receptor FtsY and the SRP itself, which consists of a polypeptide (Ffh) and a structural RNA. Also included in this property are two peptidases. Signal peptidase I cleaves the standard signal peptide, and differs from the signal peptidase used for lipoproteins. Signal peptide peptidases are enzymes that degrade the signal peptides, oligopeptides that may have signaling roles and also that may interfere with protein secretion, left after removal from a nascent protein by some signal peptidase. |
