| Accepted name: |
signal peptidase II |
| Reaction: |
Release of signal peptides from bacterial membrane prolipoproteins including murein prolipoprotein. Hydrolyses -Xaa-Yaa-Zaa┼(S,diacylglyceryl)Cys-, in which Xaa is hydrophobic (preferably Leu), and Yaa (Ala or Ser) and Zaa (Gly or Ala) have small, neutral sidechains |
| Other name(s): |
premurein-leader peptidase; prolipoprotein signal peptidase; leader peptidase II; premurein leader proteinase |
| Comments: |
An 18-kDa enzyme present in bacterial inner membranes. Inhibited by pepstatin and the antibiotic globomycin. Type example of peptidase family A8. |
