Abstract:
The evolutionary significance of the system utilizing D-amino acid enantiomers in living organisms is discussed, based on an experiment in which the mutant from Escherichia coli K--12 4627 grown on D-tryptophan was used. The mutant shows the ability of D-tryptophan is degraded to indol which can be utilized for the synthesis of L-tryptophan in the presence of serine.
