Required for morphogenesis under gluconeogenic growth conditions. Required, in gluconeogenic growth conditions, for the correct localization of PBP1 and hence for displaying a normal rod shape. Organized into coiled helical structures extending from one pole to the other. Localization does not require MreB. Deletion leads to growth defects when cells are grown on minimal medium containing ribose, gluconate, citrate, fumarate or succinate, but does not affect growth and morphology on minimal medium containing glycolytic substrates such as glucose, sucrose or glycerol. Mutants exhibit media-dependent filamentous or L-shape-like aberrant morphologies. When bacteria are grown on a gluconeogenic carbon source, overproduction can restore a normal rod-shaped morphology in a mreB mutant by rescuing the PBP1 localization. Belongs to the gluconeogenesis factor family.
