Proteolytic Cleavage Sequence The signal sequence (SS) for the phaZ1 gene product of Paucimonas lemoignei, a polyhydroxybutyrate depolymerase (1) . In the native protein the signal sequence is cleaved between residues Ala37 and Leu38. Park et al. have showed that the fusion of the complete phaZ1 gene (including SS) and a truncated ice nucleation protein from Pseudomonas syringae (BBa_K265008), could lead to stable expression and secretion of the phaZ1 gene product. We propose that the signal sequence might be generally useful as a cleavage tag in secretion systems that include a membrane anchor component, such as INPNC (BBa_K265008) or OmpA (BBa_K103006). The proposed constructs would consists of a membrane anchor (INPNC or OmpA) followed by the cleavable signal sequence and finally a target protein marked for secretion.
