Pathology & Biotechi

Disruption phenotypei

Single mutation, decreased extracellular putrescine, in an sapBCDF operon deletion no change in resistance to antimicrobial peptide LL-37. Operon deletion has no effect on growth, but if the putrescine importer PuuP is also deleted then growth is slower.1 Publication

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.
