Targets
- General Function:
- Lysozyme activity
- Specific Function:
- 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.
- Gene Name:
- E
- Uniprot ID:

- General Function:
- Nicotinate-nucleotide-dimethylbenzimidazole phosphoribosyltransferase activity
- Specific Function:
- Catalyzes the synthesis of alpha-ribazole-5'-phosphate from nicotinate mononucleotide (NAMN) and 5,6-dimethylbenzimidazole (DMB).
