We study pursuit-evasion in a polygonal environment with polygonal obstacles. In this turn based game, an evader e is chased by pursuers p 1 , p 2 ,. .. , p. The players have full information about the environment and the location of the other players. The pursuers are allowed to coordinate their actions. On the pursuer turn, each p i can move to any point(More)
A mutant of E. coli that lacks leucyl,-phenylalanyl-tRNA-protein transferase (EC has been isolated. Ability to produce the two activities could be introduced into the mutant from an F' strain whose episome contains genetic material located between 45 and 54 min on the E. coli chromosome. When grown into stationary phase and resuspended in minimal(More)
A mutant of Saccharomyces cerevisiae deficient in arginyl-tRNA-protein transferase has been isolated. The responsible mutation designated ate1, was localized near the centromere of chromosome VII. It probably involves the structural gene for the transferase since residual enzyme activity in the mutant is temperature-sensitive.
A general strategy for the insertion of nuclear spin labels throughout the sequence of a protein is illustrated with the Escherichia coli lac repressor. Examples are shown where the 19F nucleus is incorporated using 3-fluorotyrosine, as well as the selective insertion of additional protons. These selectively inserted nuclei give additional resonances in the(More)
