The nodPQ genes in Azospirillum brasilense Sp7 are involved in sulfation of lipopolysaccharides

Environ Microbiol. 2005 Nov;7(11):1769-74. doi: 10.1111/j.1462-2920.2005.00930.x.

Abstract

Here we report on the presence of sulfated lipopolysaccharide molecules in Azospirillum brasilense, a plant growth-promoting rhizosphere bacterium. Chemical analysis provided structural data on the O-antigen composition and demonstrated the possible involvement of the nodPQ genes in O-antigen sulfation.
