Only One of Three Bcs1 Homologs in Aspergillus fumigatus Confers Respiratory Growth.

ABSTRACT: The mitochondrial translocase Bcs1 is required for the correct assembly of complex III of the mitochondrial respiratory chain. Because of its importance, Bcs1 was recently proposed as a target for antifungal agents. The function of this AAA (ATPase Associated with diverse cellular Activities) protein has been extensively characterized in Saccharomyces cerevisiae. This yeast as well as previously studied mammals each encode only one homolog. In contrast, the pathogenic mold Aspergillus fumigatus encodes three putative Bcs1 homologs, none of which have been characterized to date. To study the role of these three homologs in A. fumigatus, conditional and deletion mutants of the respective genes AFUA_3G13000 (bcs1A), AFUA_4G01260 (bcs1B), and AFUA_2G14760 (
