Sequence comparison between TmYjeQ and its homologues. Bs, B. subtilis; Ec, E. coli; Pp, Pseudomonas putida; Mpe, Mycoplasma penetrans HF-2; Mp, Mycoplasma pneumoniae. Domains are represented as by the following colors: the OB-fold domain (yellow), the GTPase domain (light blue), and the zinc-finger domain (pink). G1 and G2, representing the 310-helices, are green. The G-1 to G-5 region of characteristic GTPase loops is purple. Green characters represent the conserved residues present in more than five species. –, gaps; *, all conserved residues. Colons represent homologous residues having hydrophobic side chains, and periods represent homologue residues having polar side chains. The whole-sequence identities of Bs, Ec, Pp, Mpe, and Mp against TmYjeQ are 38.3%, 34.2%, 33.2%, 32.5%, and 26.4%, respectively. The whole-sequence identities against the OB-fold domain are 21.2%, 16.7%, 22.7%, 19.7%, and 18.2%, respectively. The whole-sequence identities against the GTPase domain are 43.1%, 38.9%, 38.3%, 37.7%, and 29.9%, respectively. The whole-sequence identities against the zinc-finger domain are 43.5%, 40.3%, 30.6%, 32.3%, and 25.8%, respectively.
