STRUCTURE DETERMINATION OF UMUD' BY MAD PHASING OF THE SELENOMETHIONYL PROTEIN
Overview
For life to be sustained, mistakes in DNA repair must be tolerated when, damage obscures the genetic information. In bacteria such as Escherichia, coli, DNA damage elicits the well regulated 'SOS response'. For the, extreme case of damage that cannot be repaired by conventional enzymes, there are proteins that allow the replication of DNA through such lesions, but with a reduction in the fidelity of replication. Essential proteins in, this mutagenic process are RecA, DNA polymerase III, UmuD, UmuD' and UmuC, (umu: UV mutagenesis). Regulation of this response involves a, RecA-mediated self-cleavage of UmuD to produce UmuD'. To understand this, system in more detail, we have determined the crystal structure of the E., coli UmuD' mutagenesis protein at 2.5 A resolution. Globular heads ... [(full description)]
