Abstract
The nucleotide sequence of a 1.9 Kb HindIII fragment of DNA derived from the arom locus of A.nidulans and encoding the biosynthetic dehydroquinase activity has been determined. The sequences encoding the biosynthetic and catabolic dehydroquinase enzymes of A.nidulans show no detectable homology, strongly suggesting convergent evolutionary pathways. The messenger RNA specified by the arom locus was detected as a 5.3 Kb RNA species.
