Signal peptidase II (EC 3.4.23.36, premurein-leader peptidase, prolipoprotein signal peptidase, leader peptidase II, premurein leader proteinase) is an enzyme.[1][2][3] This enzyme catalyses the following chemical 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

This enzyme is present in bacterial inner membranes.
