Purification and characterization of phiX174 gene A protein. A multifunctional enzyme of duplex DNA replication.

Synthesis of phiX174 viral (+) strand circles in vitro requires gene A protein, rep protein, DNA binding protein, and DNA polymerase III holoenzyme (Eisenberg, S., Scott, J. F., and Kornberg, A., (1976) Proc. Natl. Acad. Sci. U.S.A. 73, 3151-3155). We have used this reaction as an assay to isolate gene A protein in greater than 90% purity. Its molecular weight under denaturing conditions is 59,000. The protein tends to aggregate and lose activity at low ionic strength. Tritium-labeled gene A protein cleaves the phiX174 duplex replicative form and is bound to it in a 1:1 ratio as part of an active replication complex. The attachment, at the 5' phosphoryl end of the cleavage point, is apparently covalent. The complex was not dissociated by: (i) banding in CsCl, (ii) treatment with 0.2 M NaOH, or (iii) boiling in 1% sodium dodecyl sulfate and electrophoresis on a sodium dodecyl sulfate-acrylamide gel; only micrococcal nuclease digestion of the DNA released the protein.[1]
