Novel subfamily of mitochondrial HMG box-containing proteins: functional analysis of Gcf1p from Candida albicans.

ABSTRACT: Mitochondria of eukaryotic organisms contain populations of DNA molecules that are packed into higher-order structures called mitochondrial nucleoids (mt-nucleoids). In Saccharomyces cerevisiae, the compaction of mitochondrial DNA (mtDNA) into mt-nucleoids is mediated primarily by the high-mobility group (HMG) box-containing protein Abf2, which is an important player in stabilization and metabolism of mtDNA. Although it is evident that analogous proteins must exist in other yeast species, an apparently fast divergence rate has precluded their identification, characterization and comparative analysis. Using in silico analysis of the complete genome sequence of the pathogenic yeast Candida albicans we predicted that the ORF 19.400/19.8030 assigned as GCF1 encodes a putative mitochondrial HMG
