Pathology & Biotechi

Disruption phenotypei

A transposon mutant in galU (only the first 220 residues could be expressed) allows HeLa cell invasion but no cell spreading. Shows decreased secretion of IscA, a protein required for cell spreading. The lipopolysaccharide produced is of a size consistent with it containing only lipid A and a single core component.1 Publication
