Figure 2

Multiple alignment of the double-psi β-barrel (DPBB) domains from the β' subunit of DNA-dependent RNA polymerases with the predicted DPBB domains of RNA-dependent RNA polymerases. The conventions for naming sequences and coloring conserved residues are as described in the legend to Figure 1. The shared secondary structure elements are shown above the alignment with E denote the β-strand (extended) conformation. Non-conserved regions are depicted as numbers with inserts. The species abbreviations are as in figure Fig. 1. The species abbreviations that are not listed in the legend to Figure 1 are: Thth: Thermus thermophilus, Dr: Deinococcus radiodurans, Ec: Escherischia coli, Atu: Agrobacterium tumefaciens, Mlo: Mesorhizobium loti, Hp: Helicobacter pylori, Uu:Ureaplasma ureolyticum, Bs: Bacillus subtilis, Tm: Thermotoga maritima, Ssp: Synechocystis species, Aae: Aquifex aeolicus, Ct Chlamydia trachomatis, Mpn Mycoplasma pneumoniae, Mtu: Mycobacterium tuberculosis, Tp: Treponema pallidum, Sso: Sulfolbus solfataricus, Ap: Aeropyrum pernix, Mac: Methanosarcina acetivorans, Hsp: Halobacterium species, Sc: Saccharomyces cerevisiae, Hs: Homo sapiens, VV: Vaccinia virus, BNV: Bombyx mori Nuclear Polyhedrosis virus, Cgl: Corynebacterium glutamicum, Klla: Kluyveromyces lactis.
