sapF

Functionⁱ

Part of a putrescine export transport system, does not play a role in resistance to antimicrobial peptides (PubMed:27803167). Does not stimulate K⁺ uptake ability of TrkH on its own, but increases K⁺ uptake by 20% in the presence of SapD; has no effect of TrkG (PubMed:11700350).2 Publications

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.
