(A) Effect of the order of addition on S. pombe Dmc1-Hop2-Mnd1 D-loop formation in Mg2+ or Ca2+ buffer. Reactions with Dmc1 (4 μM) and Hop2-Mnd1 (1 μM) were performed for 5 min (lanes a–d) or 30 min in MgCl2 (2.5 mM) (lanes e–h) or 5 min (lanes i–l) or 30 min (lanes m–p) in CaCl2 buffer. (2.5 mM). (B) SpH2M1 does not stimulate spRad51. Indicated concentrations of spRad51 and spH2M1 were used (lanes a–f) and mammalian Dmc1 and Hop2-Mnd1 reaction is shown for comparison (lane g). (C) SpH2M1 interacts with both spDmc1 and spRad51. Purified His-tagged spH2M1 was incubated with affinity beads containing crosslinked BSA (lane a), spRad51 (lane b), or spDmc1 (lane c). Eluted material was probed by western blotting using anti-His antibody.
