CONFORMATIONAL FLEXIBILITY REVEALED BY THE CRYSTAL STRUCTURE OF A CRENARCHAEAL RADA

Overview

Homologous recombinational repair is an essential mechanism for repair of, double-strand breaks in DNA. Recombinases of the RecA-fold family play a, crucial role in this process, forming filaments that utilize ATP to, mediate their interactions with single- and double-stranded DNA. The, recombinase molecules present in the archaea (RadA) and eukaryota (Rad51), are more closely related to each other than to their bacterial counterpart, (RecA) and, as a result, RadA makes a suitable model for the eukaryotic, system. The crystal structure of Sulfolobus solfataricus RadA has been, solved to a resolution of 3.2 A in the absence of nucleotide analogues or, DNA, revealing a narrow filamentous assembly with three molecules per, helical turn. As observed in other RecA-family recombinases, each ... [(full description)]
