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. The KhpA-KhpB complex stimulates or controls elongasome-mediated lateral cell wall biosynthesis. It is not clear what is the function of the KhpA homooligomer in vivo. Self-associates, makes at least homodimers. Interacts with KhpB (also called EloR) via the KH domain of KhpB. The complex with KhpB is critical for regulating elongasome activity and for KhpA localization at midcell. Some protein localizes to the division zone with FtsZ throughout the cell cycle, the rest remains in the cytoplasm. Cells grow more slowly, are rounder with less elongation, form short chains. Belongs to the KhpA RNA-binding protein family.
