Abstract
Escherichia coli pgsA3 mutants deficient in acidic phospholipids were found to be defective in flagellar formation. This was first noticed b y the unusual protein patterns of outer membrane fractions and was con firmed by measuring whole-cell total flagellin. pgsA3 mutants were com pletely nonmotile. The defects were suppressed by a plasmid carrying t he pgsA coding region. Flagellin levels and motility of null cls mutan ts that lacked cardiolipin synthase were almost normal. We conclude th at the flagellum synthesis in E. coli is dependent on the membrane lev els of acidic phospholipids.
