Chorismate synthase catalyzes the last common step in the biosynthesis of the three aromatic amino acids in microorganisms and plants. We have cloned a cDNA for this enzyme from the higher plant Corydalis sempervirens. This is the first chorismate synthase cDNA from a eukaryotic organism. The nucleotide sequence was determined and the identity of the cDNA was confirmed by the amino acid sequence of tryptic peptides obtained from purified chorismate synthase. The homology to the two known bacterial sequences is about 48%. The cDNA contains an open reading frame of 1341 base pairs, encoding a protein of 447 amino acids. This protein with a molecular mass of 48,100 daltons resembles a chorismate synthase precursor targeted for chloroplast import. Multiple sites of polyadenylation were observed in chorismate synthase mRNAs.
