RNA-dependent ATPase from Saccharomyces cerevisiae.


A new RNA-dependent ATPase has been isolated from yeast chromatin extracts and partially characterized. The protein has a sedimentation coefficient of about 7 S. The enzyme hydrolyzes specifically ATP (or dATP) to ADP (or dADP) and Pi in the presence of Mg2+ or Mn2+ ions and requires a single-stranded polynucleotide as cofactor. The order of efficiency of… (More)
