FIG. 1.
Analysis of O. tsutsugamushi autotransporter proteins. (A) Schematic representation of the five Sca proteins identified in the genome of the O. tsutsugamushi Boryong strain. The domain structures were predicted using SMART (Simple Modular Architecture Research Tool; http://smart.embl-heidelberg.de/). *, cloned region of ScaC33-232 used in this study; SP, signal peptide; RPT, internal repeat sequence; TM, transmembrane; AT, autotransporter domain; aa, amino acids. (B) Phylogenetic tree of the sca genes identified in the genome of Boryong (OTBS) and Ikeda (OTT) strains. The five groups of ortholog genes are indicated on the right-hand side.
