| DNA Binding | |
| EC Number | 3.4.21.89 |
| Enzyme Function | FUNCTION: Catalytic component of the signal peptidase complex (SPC) which catalyzes the cleavage of N-terminal signal sequences from nascent proteins as they are translocated into the lumen of the endoplasmic reticulum (By similarity). Specifically cleaves N-terminal signal peptides that contain a hydrophobic alpha-helix (h-region) shorter than 18-20 amino acids (By similarity). {ECO:0000250|UniProtKB:P15367, ECO:0000250|UniProtKB:P67812}. |
