Molecular Study of the Interaction of Azospirillum lipoferum with Wheat Germ Agglutinin
Capsular receptors of Azospirillum lipoferum SpBrl7 involved in interaction with wheat germ agglutinin have been studied. In the capsular fraction of bacteria two putative receptors were detected, a 25 kDa protein/glycoprotein and a complex of about 100 kDa. No attachment of wheat germ agglutinin to the corresponding capsular components was found in the wheat germ agglutinin-nonbinding mutant of A. lipoferum, as expected. The Tn2706 transposon insertion of the mutant has been localized.
