✦ Synopsis

The nuclear gene coding for the mitochondrial subunit 9 of the F0F1-ATP synthase complex was isolated from a genomic library of Podospora anserina. Nucleotide sequencing revealed an open reading frame capable to code for 144 amino acids including an amino-terminal pre-sequence of 63 amino acid residues for mitochondrial import of the pre-proteolipid. The P. anserina proteolipid shows extensive sequence identity with the corresponding gene products of the related filamentous fungi Neurospora crassa, Aspergillus nidulans and Aspergillus niger. In contrast to the situation in Saccharomyces cerevisiae, N. crassa and A. nidulans, no sequence similarity of the ATP synthase subunit 9 gene to the mitochondrial genome of P. anserina could be detected. Thus, in P. anserina this gene appears to be exclusively encoded by the nuclear genome.
