Research has elucidated the properties of a phage-derived antibacterial, with one study focusing on KP27 endolysin and its robustness to pH and temperature. Another study examined the structure and function of the Ts2631 endolysin from a Thermus scotoductus phage. The findings appear to involve the characterization of endolysins, which are enzymes that break down peptidoglycan in bacterial cell walls.
