EPTG_00019

Functionⁱ

Endolysin with amidase 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 breaking down the peptidoglycan layer.UniRule annotation

Plays an important role in the switch between viral transcription and genome replication. Once produced in sufficient amount, interacts with and inhibits the viral RNA polymerase that becomes unable to produce additional late transcripts. This lysozyme-polymerase complex in turn plays an active role in viral genome replication and packaging.UniRule annotation

Catalytic activityⁱ

Hydrolyzes the link between N-acetylmuramoyl residues and L-amino acid residues in certain cell-wall glycopeptides.UniRule annotation

Cofactorⁱ

Zn²⁺UniRule annotationNote: Zn²⁺ is required for amidase activity.UniRule annotation

Activity regulationⁱ

Binding to the viral RNA polymerase inhibits amidase activity.UniRule annotation
