Chains	Enzyme Name	Description	Catalytic Residues
A	lysozyme (glycosyl hydrolase 24 family) M-CSA #921	Endolysin with lysozyme activity 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 permeabilised the host cell membrane, the endolysin can reach the periplasm and break down the peptidoglycan layer.
