Protein

Signal peptidase complex catalytic subunit SEC11

Gene

SEC11

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Catalytic component of the signal peptidase complex (SPC), which catalyzes the cleavage of N-terminal signal sequences of proteins targeted to the endoplasmic reticulum. Signal peptide cleavage occurs during the translocation (cotranslationally or post-translationally) through the translocon pore into the endoplasmic reticulum.4 Publications

Miscellaneous

Present with 3150 molecules/cell in log phase SD medium.1 Publication

Catalytic activityi

Cleavage of hydrophobic, N-terminal signal or leader sequences from secreted and periplasmic proteins.
