CC   -!- FUNCTION: Could be involved in the inhibition of exopolysaccharide
CC       synthesis (EPS) and nodulation ability (nod).
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Multi-pass membrane
CC       protein {ECO:0000305}.
CC   -!- SIMILARITY: To Rhizobium exopolysaccharide production repressor protein
CC       (ExoX). {ECO:0000305}.
