the major polypeptide chain present ( 58,000 daltons ) is shown to cosediment with a dna-dependent gtpase ( and atpase ) activity , and to induce extensive in vitro dna synthesis on both single- and double-stranded dna templates when incubated with our preparations of five other purified t4 dna replication proteins ( plus deoxyribonucleoside and ribonucleoside triphosphates ) .
