Cloning, expression and structure determination of SH3b cell wall binding domain of bacteriophage 812 endolysin
Original language description
In this study we focused on endolysin of staphylococcal bacteriophage 812, a member of unclassified SPO1-like viruses from family Myoviridae. The endolysin of phage 812 includes three domains: two catalytic domains and the SH3b-domain that is probably acell wall targeting domain, which could be responsible for binding of endolysin to peptidoglycan. The gene sequence for the C-terminal SH3b domain was cloned in pET28 vector and expressed as a soluble protein in E. coli BL21 (DE3) to determine the 3D structure of the protein. A native variant of the SH3b protein was purified without the his-tag. Subsequently, three variants of this protein have been prepared: (i) non-labeled, (ii) single-labeled (15N) and (iii) double-labeled (13C, 15N) domain. The protein was purified to homogeneity using ammonium sulphate precipitation, anion exchange chromatography, cation exchange chromatography, and gel filtration.
