A probable RNA chaperone. Forms a complex with KhpB which binds to cellular RNA and controls its expression. Plays a role in peptidoglycan (PG) homeostasis and cell length regulation. Probably plays a role in PG homeostasis and regulating peripheral PG synthesis. Forms a complex with KhpB. Grows slowly and is smaller than wild-type; estimated to be about 50% of the volume of wild-type cells. Belongs to the KhpA RNA-binding protein family.
