Actinomyces oris is an oral bacterium important for the development of dental plaque. It expresses two forms of fimbriae: type 1 and type 2. FimP, which is the fimbrial protein that is polymerized into the stalk of the type 1 fimbriae, was cloned, overexpressed and crystallized. X-ray data were collected and processed to 2.2 Å resolution. The crystals belonged to space group P21212, with one molecule in the asymmetric unit. To facilitate structure determination using single anomalous dispersion, three methionines were introduced by site-directed mutagenesis. Crystals of selenomethionine-labelled protein were obtained by streak-seeding and diffracted to 2.0 Å resolution.
