Predicted clashes in EB hybrids are shown for all single crossover EB hybrids. A clash between any two residue positions is shown as an arc. The specific activity (μmol/min per mg) and number of clashes in each hybrid are also shown. Note that the 0 and 159 crossover positions correspond to the parental B. subtilis and E. coli DHFR sequences, respectively.
