1		8		RecA5 fusion protein was incubated with a 3-fold molar excess of ssDNA in the original protein buffer supplemented with 2 mM ADP, 10 mM MgCl2 and 8 mM AlF4, pH 6.0. Crystals of the RecA5-(ADP-AlF4-Mg)5-(dT)15 complex were grown from 50 mM Tris-Cl, 9% (w/v) PVP K15, 32% (v/v) MPD, 10 mM DTT, pH 8.0. RecA5-(ADP-AlF4-Mg)5-(dT)15-(dA)12 complex were obtained by soaking the RecA5-(ADP-AlF4-Mg)5-(dT)15 crystals in a 0.2 mM solution of the complementary (dA)12 oligonucleotide in 25 mM Tris-Cl, 9% (w/v) PVP K15, 32% (v/v) MPD, 2 mM ADP, 8 mM AlF4, and 10 mM MgCl2 for 4 hr.
