Structure and function of the N-terminal 40 kDa fragment of human PMS2: a monomeric GHL ATPase.
A.Guarné, M.S.Junop, W.Yang.
 
  ABSTRACT  
 
Human MutLalpha, a heterodimer of hMLH1 and hPMS2, is essential for DNA mismatch repair. Inactivation of the hmlh1 or hpms2 genes by mutation or epigenesis causes genomic instability and a predisposition to hereditary non-polyposis cancer. We report here the X-ray crystal structures of the conserved N-terminal 40 kDa fragment of hPMS2, NhPMS2, and its complexes with ATPgammaS and ADP at 1.95, 2.7 and 2.7 A resolution, respectively. The NhPMS2 structures closely resemble the ATPase fragment of Escherichia coli MutL, which coordinates protein-protein interactions in mismatch repair by undergoing structural transformation upon binding of ATP. Unlike the E.coli MutL, whose ATPase activity requires protein dimerization, the monomeric form of NhPMS2 is active both in ATP hydrolysis and DNA binding. NhPMS2 is the first example of a GHL ATPase active as a monomer, suggesting that its activity may be modulated by hMLH1 in MutLalpha, and vice versa. The potential heterodimer interface revealed by crystallography provides a mutagenesis target for functional studies of MutLalpha.

Figure 2.
Figure 2 Structure of NhPMS2. (A and B) Orthogonal views of NhPMS2 structure in ribbon diagram. -strands are shown as purple arrows, and 3[10] helices as gold ribbons and connecting loops as light green coils. Disordered loops are shown as green dotted lines. Secondary structures are labeled using the same convention as for the LN40 structure. New structural elements in NhPMS2 are labeled with the same name as the following structural element with a prime (E' helix lies between D and E helices). N- and C-termini are marked for clarity. (C) Sequence alignment of hPMS2, hMLH1 and MutL. Loops undergoing structural transformation in LN40 are labeled and shown in orange. ATP binding motifs (I -IV) are boxed in blue. The residues conserved in the GHL superfamily are shaded in blue, the rest of the conserved residues are shaded in light yellow.
Figure 4.
Figure 4 Comparison of the active site of LN40 and NhPMS2. (A) Ribbon diagram of the constant part of the ATP binding site. Superimposition of NhPMS2 (gold), LN40 -ADPnP (green) and apo-LN40 (blue) encompassing motifs I, II and IV, and helices B and D is shown in stereo. (B -E) Ribbon diagrams of the complete ATP binding site of apo-LN40 (B), LN40 complexed with ADPnP (C), apo-NhPMS2 (D), and NhPMS2 complexed with ATP S (E). The ATP lids are shown in solid magenta when traceable. The start and end residues of the ATP lid of NhPMS2 structures are labeled and marked with red and blue arrowheads, respectively. Side chains of conserved residues involved in nucleotide binding are shown as ball-and-sticks. Arg95 of LN40 and its equivalent, Arg107 of hPMS2, are shown as magenta ball-and-sticks. The bound nucleotide is shown as a gray stick model.
