SSB inhibits RecA nucleoprotein filament assembly. (AC) Schematic illustration of the experimental setup and representative bead BM time-courses of RecA E38K assembly on various DNA substrates: (A) (dT)35; (B) (dT)100 and (C) (dT)100 wrapped with a SSB tetramer. The reaction condition prepared the (SSB)65 binding mode as previously documented. RecA filament assembly leads to the apparent bead BM increase. (D) Mean nucleation time (second) and (E) mean extension time (second/RecA) of RecA E38K assembling on these DNA substrates. Error bar is one standard error of the mean.
