Structural analyses of gp45 sliding clamp interactions during assembly of the bacteriophage T4 DNA polymerase holoenzyme. II. The Gp44/62 clamp loader interacts with a single defined face of the sliding clamp ring

The phage T4 gp45 sliding clamp is a ring-shaped replication accessory protein that is mounted onto DNA in an ATP-dependent manner by the gp44/62 clamp loader. In the preceding paper (Pietroni, P., Young, M. C., Latham, G. J., and von Hippel, P. H. (1997) J. Biol. Chem. 272, 31666-31676), two gp45 m...
