Pharmaceutical usei

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.

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
