== Function ==
 +
[https://www.uniprot.org/uniprot/CITA_KLEPN CITA_KLEPN] Member of the two-component regulatory system CitA/CitB. Probably activates CitB by phosphorylation. The periplasmic domain binds H-citrate(2-), which is essential for induction of the citrate-fermentation genes.<ref>PMID:10447894</ref>
