Function

ENLYS_BPT4 Endolysin with lysozyme activity that degrades host peptidoglycans and participates with the holin and spanin proteins in the sequential events which lead to the programmed host cell lysis releasing the mature viral particles. Once the holin has permeabilized the host cell membrane, the endolysin can reach the periplasm and break down the peptidoglycan layer.[1]

Publication Abstract from PubMed

Measurements of changes in structure and stability caused by 13 different substitutions for threonine 157 in phage T4 lysozyme show that the most stable lysozyme variants contain hydrogen bonds analogous to those in the wild-type enzyme and that structural adjustments allow the protein to be surprisingly tolerant of amino-acid substitutions.
