We have isolated the cDNA and corresponding genomic DNA for the ilv-2 locus of Neurospora crassa. This gene encodes alpha-keto-beta-hydroxylacyl reductoisomerase (Ilv-2), required for the synthesis of isoleucine and valine. The gene contains four introns, maps to the right arm of chromosome V, and encodes a protein of 400 amino acids (aa). Alignment of the aa sequence of Ilv-2 with the two other known eukaryotic sequences encoding this enzyme reveals two conserved regions.
