Phylogenetic analysis by neighbor-joining of putative
two-component open reading frames (ORFs) from the response
regulator I orphans arr7, arr10, arr12 and
arr14. Group arr7 =
HaloVNG0974G, AfulAF1042, MmarMMP0933, Mbur_401647540,
MaceMA3068, MmazMM0330, PAB1330, PH0482, HmarrnAC2194,
Tkod_610170400 , Mhun_401793100 and NphaNP2102A; group
arr10 = MaceMA0016, MbarA_0986 and MmazMM1327;group arr12 = MaceMA4376, MbarA_1051,
MmazMM1068, AfulAF2419, Mbur_401644620 and Mhun_401789540; and
group arr14 = MaceMA2445, MbarA_3109,
MMAZMM3007, Mbur_401658280 and Mhun_401776210. The bacterial
ORFs are CtetaniE88, Tmaritima and Gmetallired. Abbreviations:
CtetaniE88 = C. tetaniE88_1817150; Tmaritima =
T. maritimaMSB8_24050; and Gmetallired =
