Abstract

Some enzymes of the terminal steps of phenylalanine and tyrosine biosyntheses were investigated in various alkaloid-forming ergot strains. All strains studied utilize both arogenate and phenylpyruvate as an intermediate in L-phenylalanine synthesis. L-Tyrosine is preferentially or exclusively synthesized via the arogenate pathway. No feedback inhibition of arogenate pathway enzymes by aromatic amino acids was observed.
