Inner membrane protein YqjA

Gene

yqjA

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

May be a membrane transporter required for proton motive force (PMF)-dependent drug efflux. Required, with YghB, for the proper export of certain periplasmic amidases and, possibly, other Tat substrates. May play a role in determining membrane lipid composition.3 Publications

Pathology & Biotechi

Disruption phenotypei

Double mutants lacking both yghB and yqjA show incomplete cell division, temperature sensitivity and altered phospholipid levels. They are also hypersensitive to several compounds known to be exported by other drug efflux proteins, including ethidium bromide, methyl viologen, acriflavine and beta-lactam antibiotics. Expression of either yghB or yqjA can restore the wild-type phenotype, suggesting that these proteins have redundant functions. Both individual null mutant strains grow normally at all temperatures.3 Publications

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.
