SwmB, a 1.12-megadalton protein that is required for nonflagellar swimming motility in Synechococcus

J Bacteriol. 2007 Feb;189(3):1158-62. doi: 10.1128/JB.01500-06. Epub 2006 Dec 8.


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.
