Figure 3. Sequence conservation in NusB.

Figure 3

a, Sequence alignment of NusB orthologs. Amino acids identical to the E. coli sequence are highlighted in green. Amino acids that represent a conservative substitution from the E. coli sequence are highlighted in orange. Amino acids that are identical across all NusB sequences are marked by a solid arrow. Amino acid positions with only conserved substitutions across all sequences are marked by an open arrow. b, Localization of conserved residues on NusB. The side chains of conserved or identical residues across all NusB proteins are displayed and labeled.
