The domains of human fibronectin mediating the binding of alpha antigen, the most immunopotent antigen of mycobacteria that induces protective immunity against mycobacterial infection.

Abstract excerpt

We have recently shown that alpha antigen (alpha-Ag), the immunodominant antigen of mycobacteria, has a novel fibronectin (FN)-binding motif that is unique among mycobacteria [Naito, Ohara, Matsumoto and Yamada (1998) J. Biol. Chem. 273, 2905-2909]. In this study, we examined the domains of human FN that interacted with alpha-Ag. Fragments of FN generated by either proteolysis or recombinant DNA techniques were...
