Protein

Flagellum-specific ATP synthase

Gene

fliI

Organism
Salmonella typhimurium (strain LT2 / SGSC1412 / ATCC 700720)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Probable catalytic subunit of a protein translocase for flagellum-specific export, or a proton translocase involved in local circuits at the flagellum. May be involved in a specialized protein export pathway that proceeds without signal peptide cleavage.

Catalytic activityi

ATP + H2O + H+(In) = ADP + phosphate + H+(Out).PROSITE-ProRule annotation
