A conserved fold for fimbrial components revealed by the crystal structure of a putative fimbrial assembly protein (BT1062) fromBacteroides thetaiotaomicronat 2.2 Å resolution

This is the authors' abstract. We don't add key points for this paper.

BT1062 from Bacteroides thetaiotaomicron is a homolog of Mfa2 (PGN0288 or PG0179), which is a component of the minor fimbriae in Porphyromonas gingivalis. The crystal structure of BT1062 revealed a conserved fold that is widely adopted by fimbrial components.
