Identification of a functionally important loop in Salmonella typhimurium ArnT.

Biochemistry - 12 Jan 2010

Impellitteri Nicholas A, Merten Jacqueline A, Bretscher Lynn E, Klug Candice S

Abstract excerpt

ArnT confers resistance to the antibiotic polymyxin in Salmonella typhimurium and Escherichia coli through the modification of lipid A, a major component of the outer surface of gram-negative bacteria. ArnT transfers a neutral aminoarabinose moiety onto the negative phosphate groups of lipid A, r...
