== Function == | |||
[https://www.uniprot.org/uniprot/ENLYS_BPT4 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.<ref>PMID:22389108</ref> | |||

== Publication Abstract from PubMed == | |||
Replacing the isoleucine at amino-acid position three of bacteriophage T4 lysozyme causes changes in the thermodynamic stability of the protein that are directly related to the hydrophobicity of the substituted residue. Structural analysis confirms that the hydrophobic stabilization is proportional to the reduction of the surface area accessible to solvent on folding. | |||
