when tested with several highly purified dna polymerases ( dna nucleotidyltransferase , ec 2.7.7.7 ) , the factors show a much greater stimulation of homologous , non-mitochondrial enzymes ( rat liver nuclear- , rat liver cytoplasmic- , or novikoff-dna polymerases ) when compared with rat liver or calf liver mitochondrial- , escherichia coli i- , or sea urchin nuclear-dna polymerases .
