Oligogalacturonate-specific porins (KdgM) are a family of outer bacterial membrane proteins from Erwinia chrysanthemi. The phytopathogenic Gram-negative bacteria E. chrysanthemi secretes pectinases which are able to degrade the pectic polymers of plant cell walls and uses the degradation products as a carbon source for growth. Synthesis of KdgM is strongly induced in the presence of pectic derivatives.
