Revised Manuscript Received August 10, 1993• abstract: We have recently shown that the expression of a collagen adhesin is both necessary and sufficient to mediate the attachment of Staphylococcus aureus to cartilage, a complex collagen-containing substrate [Switalski, LM, Patti, J. M., Butcher, W., Gristina, A. G., Speziale, P., & Hook, M.(1993) Mol. Microbiol. 7, 99-107]. We now report on the localization of the ligand binding site within the 135-kDa S. aureus collagen adhesin. Using deletion mutagenesis in combination with Western ligand blot and direct binding assays, the collagen binding domain (CBD) was localized to a 168 amino acid long segment [CBD (151-318)] within the N-terminal portion of the adhesin. Using biospecific interaction analysis, pepsin-digested bovine type II collagen was found to contain eight binding sites for CBD (151-318); two binding sites were of “high” affinity (Ka= 3/iM) and six sites were of low affinity (Ka= 30/iM). Short truncations in the terminal flanking regions of CBD (151-318) resulted in two CBDs (180-318 and 151-297) that lacked collagen bindingactivity. Analysis by circular dichroism of the recombinantCBDs in the far UV revealed similar secondary structures, predominantly/3-sheet, whereas the near-UV spectra indicated dramatic changes in the degree of intermolecular packing (tertiary structure). The deduced amino acid sequence of the ligand binding domain of the collagen adhesin is presented.
