SwmB is required for swimming motility in Synechococcus sp. strain WH8102. This highly repetitive 1.12-MDa polypeptide is associated with the cell surface, where it is arranged in a punctate manner. Inactivation of swmB does not affect the localization of SwmA, an S-layer protein also required for swimming.
