'''CRYSTAL STRUCTURE OF A SITE-SPECIFIC RECOMBINASE, GAMMA-DELTA RESOLVASE COMPLEXED WITH A 34 BP CLEAVAGE SITE'''<br />


==Overview==
==CRYSTAL STRUCTURE OF A SITE-SPECIFIC RECOMBINASE, GAMMA-DELTA RESOLVASE COMPLEXED WITH A 34 BP CLEAVAGE SITE==
The structure of gamma delta resolvase complexed with a 34 bp substrate, DNA has been determined at 3.0 A resolution. The DNA is sharply bent by 60, degrees toward the major groove and away from the resolvase catalytic, domains at the recombination crossover point. The C-terminal one third of, resolvase, which was disordered in the absence of DNA, forms an arm and a, 3-helix DNA-binding domain on the opposite side of the DNA from the, N-terminal domain. The arms wrap around the minor groove of the central 16, bp, and the DNA-binding domains interact with the major grooves near the, outer boundaries of the binding site. The resolvase dimer is asymmetric, particularly in the arm region, implying a conformational adaptability, that may be important for resolvase binding to different DNA sites in the, synaptosome. It also raises the possibility of a sequential single-strand, cleavage mechanism.
