5. The synthesis pathways for amino acids were partly determined by cross-feeding experiments using microorganisms. Certain mutant forms of the microorganisms are defective in one enzyme for the pathway which helps to tease out the order of the steps. The numbers 1, 2, and 3 refer to the three enzymes in the pathway Consider the following synthetic pathway to make tyrosine Prephenate 4-hydroxy-phenyl-pyruvate Glutamate Tyrosine You are testing 3 mutants that have a genetic mutation that leads to a loss of one of the key three enzymes for the tyrosine synthetic pathway. Examine the data in the table below. The different mutant strains and wild type were grown in minimal medium supplemented with tyrosine or one of the intermediates. A “+” indicates successful growth whereas a”-indicates no growth. Strain Growth on Minimal Medium Supplemented with STRAIN | NONE | TYROSINE | PREPHENATE | 4-HY-PH- I GLUTAMATE PYRUVATE Mutant A Mutant B Mutant C Explain the results. Which enzymes are coded for by the genes in Mutants A, B and C? a. b. Look up some information in your science textbooks and appropriate sources on the internet (not Wikipedia but edu or /gov sources) to explain the importance of this synthetic pathway in microbes.
