PF10502 | Signal peptidase, peptidase S26 (Peptidase_S26) | Signal peptidase, peptidase S26 | This is a family of membrane signal serine endopeptidases which function in the processing of newly-synthesised secreted proteins. Peptidase S26 removes the hydrophobic, N-terminal, signal peptides as proteins are translocated across membranes. The ... | Domain |
