Fig. (5) Phylogenetic relationships among Ureaplasma UreD and the homologues, UreE and the homologues, UreF and the homologues, and UreG and the homologues. The BLAST program was used to search the GenomeNet website for proteins homologous to Ureaplasma UreD, UreE, UreF, and UreG of Ureaplasma parvum ATCC 27815 with E-value < 10-35, 10-25, 10-40, and 10-77, respectively. This search led to identification of 17 UreD homologues, 20 UreE homologues, 20 UreF homologues, and 21 UreG homologues. The 18 UreD, 21 UreE, 21 UreF, and 22 UreG proteins were multiple aligned using the CLUSTAL W program on the GenomeNet website. Phylogenetic tree was reconstructed, based on the multiple-alignment with complete deletion of gap sites using the neighbor-joining method of MEGA software with 1000 bootstrap replicates.
