Abstract excerpt
In order to isolate mutants with impaired uptake of branched-chain amino acids, mutants were induced which on complex medium were sensitive to an inhibitor of branched-chain amino acid biosynthesis. Eighteen mutants of independent origin were found. Ten of them were assayed for branched-chain amino acid uptake. Three of these were impaired in the uptake of L-valine, L-isoleucine and L-leucine, while the rest were...
