Cloning and sequencing of the PIF gene involved in repair and recombination of yeast mitochondrial DNA

Abstract

The nuclear gene PIF of Saccharomyces cerevisiae is required for both repair of mitochondrial DNA (mtDNA) and recognition of a recombinogenic signal characterized by a 26-bp palindromic AT sequence in the ery region of mtDNA. This gene has been cloned in yeast by genetic complementation of pif mutants. Its chromosomal disruption does not destroy the genetic function of mitochondria. The nucleotide sequence of the 3.5-kb insert from a complementing plasmid reveals an open reading frame encoding a potential protein of 857 amino acids and Mr = 97,500. An ATP-binding domain is present in the central part of the gene and in the carboxy-terminal region a putative DNA-binding site is present. Its alpha helix-turn-alpha helix motif is found in DNA-binding proteins such as lambda and lactose repressors which recognize symmetric sequences. Significant amino acid homology is observed with yeast RAD3 and E. coli UvrD (helicase II) proteins which are required for excision repair of damaged DNA.
