Genetic control of enzyme formation. Final technical report
Research progress is reported on work on tryptophan biosynthesis in Euglena gracilis and higher plants. The experimental data provide an outline of the general evolution of the pathway. Structural analyses of the pathway proteins by quantitative immunochemical methods have been completed; this was done with the anthranilate synthase-1 phosphoribosyl transferase complex in Escherichia coli. An examination of the evolution, in the Enterobacteriaceae, of the enzyme activities anthranilate synthase and anthranilate-5-1 phosphoribosyl-1-pyrophosphate phosphoribosyltransferase has been begun.
