Structural insights into lesion recognition and repair by the bacterial 8-oxoguanine DNA glycosylase MutM.
J.C.Fromme, G.L.Verdine.
MutM is a bacterial 8-oxoguanine glycosylase responsible for initiating base-excision repair of oxidized guanine residues in DNA. Here we report five different crystal structures of MutM-DNA complexes that represent different steps of the repair reaction cascade catalyzed by the protein and also differ in the identity of the base opposite the lesion (the 'estranged' base). These structures reveal that the MutM active site performs the multiple steps of base-excision and 3' and 5' nicking with minimal rearrangement of the DNA backbone.

Figure 3. Comparison of active sites from three different stages of catalysis. a, Active site structure of the rAb C recognition complex 6. The density corresponding to the C1' atom and its hydroxyl is weak, presumably owing to several rotamers about the C2'-C3' bond.

Dashes indicate hydrogen bonds, and red circles denote a van der Waals interaction. d−f, Structural formulae schematics of the mode of recognition seen in (a−c), respectively.

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 code is shown on the right.
