Structures of phi29 DNA polymerase complexed with substrate: the mechanism of translocation in B-family polymerases.
A.J.Berman, S.Kamtekar, J.L.Goodman, J.M.Lázaro, Vega, L.Blanco, M.Salas, T.A.Steitz.
Replicative DNA polymerases (DNAPs) move along template DNA in a processive manner. The structural basis of the mechanism of translocation has been better studied in the A-family of polymerases than in the B-family of replicative polymerases. To address this issue, we have determined the X-ray crystal structures of phi29 DNAP, a member of the protein-primed subgroup of the B-family of polymerases, complexed with primer-template DNA in the presence or absence of the incoming nucleoside triphosphate, the pre- and post-translocated states, respectively. Comparison of these structures reveals a mechanism of translocation that appears to be facilitated by the coordinated movement of two conserved tyrosine residues into the insertion site. This differs from the mechanism employed by the A-family polymerases, in which a conserved tyrosine moves into the templating and insertion sites during the translocation step. Polymerases from the two families also interact with downstream single-stranded template DNA in very different ways.

Figure 3.
Figure 3 Water-mediated interactions maintain sequence nonspecific binding. The C:G base pair is from the ternary1 complex, and the A:T base pair is from the ternary2 complex. Red spheres are water molecules and black dashes are hydrogen bonds. Amino acids are colored by subdomain as in Kamtekar et al (2004).
Figure 4.
Figure 4 The I/YxGG/A motif. (A) The primer and template strands from the ternary complex are shown as yellow and gray sticks, respectively. The template strand and the residues of the I/YxGG/A motif are shown as spheres. (B) The two distinct populations of Y226 are shown in sticks based on a superposition of the palm subdomain. The residues are colored by crystal structure.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB codes are shown on the right.
