Virus host

Streptococcus pneumoniae [TaxID: 1313]

Protein attributes

Sequence length	296 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Lysis of bacterial host cell wall.
Catalytic activity	Hydrolyzes the link between N-acetylmuramoyl residues and L-amino acid residues in certain cell-wall glycopeptides.
Subcellular location	Host cell wall. Note: Binds to the choline residues present in the cell wall substrate.
Pharmaceutical use	May have a use in the prevention of pneumococcal disease. Pal acts very effectively in killing 15 common serotypes of pneumococci, including highly penicillin-resistant strains. It could be used to eliminate the nasopharyngeal reservoir of these bacteria.
Sequence similarities	Contains 6 cell wall-binding repeats.
