Comparative and Evolutionary Analysis of the Bacterial Homologous Recombination Systems (original) (raw)

Regression Lines of the Substitution Rates of the Recombination Proteins Plotted against the Substitution Rates of RecA
RecA is the slowest and most ubiquitous of these proteins and its substitution rates are the _x_-axis of the plot (dashed lines indicate the RecA identity line). The regression was forced to pass through zero at intercept, and the slopes of the lines indicate the relative rapidity of the protein's evolution relative to that of RecA (varies from 1.3 for RuvB to 4.4 to RecB); the points associated with mollicutes were removed because we found these to evolve proportionally faster in RecA than in the other proteins.
