From: Interference with histidyl-tRNA synthetase by a CRISPR spacer sequence as a factor in the evolution of Pelobacter carbinolicus

Figure 8

The P . carbinolicus genome encodes fewer proteins with multiple closely spaced histidines. (a) The fraction of proteins with a given minimum number of histidines, plotted for the genomes of P. carbinolicus (black diamonds), D. acetoxidans (grey squares), G. sulfurreducens (white circles), G. metallireducens (white triangles) and G. bemidjiensis (white squares). (b) The fraction of proteins with two or more histidines and a given minimum histidine demand index, plotted for the same five genomes.
