Endolysin KZ144 originates from Pseudomonas aeruginosa bacteriophage varphiKZ. SMAP-29 originates from sheep genomic DNA.
Artilysins are an exciting class of enzyme-based antibacterials. Their name is derived from "artificial endolysin" and they exploit the lytic power of bacteriophage-encoded endolysins. Endolysins are peptidoglycan hydrolases produced at the end of the lytic cycle that pass through the cytoplasmic membrane, degrade the peptidoglycan layer and cause the osmotic lysis of the infected bacterial cell, thus liberating the progeny. Purified endolysins have been used to kill Gram-positive pathogens. Gram-negative bacteria, however, have a protective outer membrane containing lipopolysaccharide (LPS) that serves as a barrier against the peptidoglycan hydrolytic activity of endolysins from the outside.
To overcome this problem, selected polycationic or amphipathic peptides that locally destabilize the LPS layer have been covalently fused to endolysins. Biers et al. fused the sheep myeloid antimicrobial peptide (SMAP-29) to the N terminus of the endolysin KZ144 to create Artilysin Art-175. Art-175 has been shown to be a highly potent antibacterial that acts in minutes to kill virtually all Pseudomonas aeruginosa strains. [2]
BBa_K1659002 is a composite of Art-175 with the N-terminal DsbA signal peptide with a hexahistidine tag. DsbA targets recombinant proteins to the co-translational signal- recognition-particle (SRP)-dependent pathway to mediate secretion out of the bacterial chassis. [2]
