The AROM locus of A.nldulans, which governs five consecutive step3 in pre-chorismate aromatic amino acid biosynthesis, ha3 been cloned in a bacterlophage vector. The nucleotlde sequence of the locus reveals a single, open reading-frame of 4,812 base-pairs, apparently without introna. An Internal segment of the A.nldulan3 AROM sequence has extensive homology with the E.coli aroA gene that encodes the 5-enolpyruvylshlkimate 3-phosphate synthase.
