Figure 4From: Interference with histidyl-tRNA synthetase by a CRISPR spacer sequence as a factor in the evolution of Pelobacter carbinolicusPhylogeny of HisS and HisZ proteins. Pcar_1041 and orthologous proteins of Geobacteraceae cluster among true histidyl-tRNA synthetases (HisS), whereas Pcar_0202 and its orthologs cluster among the HisZ proteins, which are the regulatory subunit of ATP phosphoribosyltransferase. Confidence values are out of 500 bootstraps.Back to article page
