S.aureus killing device. Truncated lysostaphin coding sequence with IPTG inducible promoter.

Lysostaphin is a zinc metalloenzyme that has a specific lytic action against S.aureus. Lysostaphin has activities of three enzymes namely, endo-β-N-acetyl glucosamidase, N-acteyl-muramyl-L-alanine amidase, glycylglycine endopeptidase. Glycylglycine endopeptidase lyses staphylococcal cells by hydrolyzing glycylglycine bonds in the poly-glycine bridges which form cross links between glycopeptide chains in cell wall peptidoglycan of S.aureus cells. The wild-type lysostaphin gene encodes a preproenzyme, and the conversion of prolysostaphin to mature lysostaphin occurs extracellularly and involves the removal of the hydrophilic tandem repeat portion of the proenzyme. In order to directly produce mature lysostaphin, we truncate the preprolysostaphin and prolysostaphin sequence. With the inducing of IPTG, the device can erradicate S.aureus through the production and release of lysostaphin.
