Reaction
the enzyme shows specific recognition of a C-terminal tripeptide, Xaa-Yaa-Zaa, in which Xaa is preferably Ala or Leu, Yaa is preferably Ala or Tyr, and Zaa is preferably Ala, but then cleaves at a variable distance from the C-terminus. A typical cleavage is -Ala-Ala-/-Arg-Ala-Ala-Lys-Glu-Asn-Tyr-Ala-Leu-Ala-Ala. In the plant chloroplast, the enzyme removes the C-terminal extension of the D1 polypeptide of photosystem II =

membrane protein SpoIVFA + H2O
?
sequenctial processing by the enzyme together with protease 4B. The 4FA regulatory protein is composed of a globular N-terminal domain, a transmembrane helix (residues 73-90), an unstructured linker region and a compact C-terminal domain (residues 160-255, LytM-like) extending into the intermembrane space. 4B/CtpB-mediated removal of 4FA residues 131-154 induces sK maturation

Protein + H2O
?
-
endogenous cleavage of proteins with hydrophobic or nonpolar residues at their C-terminal postions. Ala is preferred at the C-terminus, Ala or Tyr at the penultimate position, and Ala or Leu at the third position from the end. The cleavage site specificity is broad, with Ala, Ser, Val, and to a lesser extent Ile, Leu, Lys or Arg, preferred at the P1 position, and these same residues plus Met, Tyr, or Trp in P1' position.
