Design Notes and Sources
We fused the 26-47 peptide sequence of flagellin to the N-terminus of Art-175 sequence without any spacer/linker peptide in between, in view of how SMAP-29 was fused to endolysin KZ144 in the same fashion. A Hisx6 tag is added at the C-terminus for ease of protein purification using metal-affinity chromatography.
Briers et al created Art-175 by fusing the sheep myeloid protein SMAP-29, which in itself is a potent broad-spectrum antimicrobial albeit with significant cytotoxicity, to the N-terminus of Pseudonomas aeruginosa bacteriophage phiKZ endolysin KZ144 to first create artilysin Art-085. Art-085 formed oligomers due to intermolecular disulfide bridges and as such three cysteine residues (Cys14, Cys23, and Cys50) were mutated into serine residues to make Art-175 [1].
The original literature describing SMAP-29 and KZ144 can be found below at [2] and [3] respectively.
