Characterization of a mitochondrial protein binding to single-stranded DNA

Abstract : A DNA-binding protein from Xenopus laevis oocyte mitochondria which has been found associated with the D-loop also shows a strong preference for single-stranded DNA. The binding to polynucleotides is dependent on the base composition, but no sequence specificity was found. This protein, called mtSSB, binds tightly and cooperatively to single-stranded DNA. By its amino-acid composition and its binding properties it appears to be similar to the singlestranded DNA-binding proteins found in prokaryotes.
