A suppressor mutation specific for a missense codon in the L-ribulokinase structural gene of the L-arabinose operon of Escherichia coli B/r enhanced L-arabinose utilization by the strain containing the missense codon. Electrophoretic comparisons of the wild-type, missense, and suppressed missense Lstrains (from I. R. Tessman and M. Abou-Sabe), containing either UGA, UAG, or UAA nonsense codons, were isolated from a lawn of E. coli CR63 Sul growing in Tris-glucose soft (0.65%) agar overlaid on 575 on May 8, 2020 by guest
