title: Identification of the probable coding region for exon 2 of cytochrome oxidase polypeptide I from Aspergillus nidulans mitochondrion.
abstract: Hypothetical protein URFe of Aspergillus nidulans mitochondrion is homologous with the amino end of cytochrome oxidase (EC 1.9.3.1) polypeptide I. Unidentified reading frame URFe does not contain a suitable initiation codon and codes for a protein with a length of only 91 residues, corresponding to about 20% of cytochrome oxidase polypeptide I. It is proposed that this region codes for the second exon of the cox 1 gene of Aspergillus mitochondrion. Possible candidates for the 2- to 3-residue amino-terminal exon 1 are discussed.
