Figure 4: Structure of the postsynaptic nucleoprotein filament. a, Structure of the RecA[5]–(ADP-AlF[4]-Mg)[5]–(dT)[15]–(dA)[12] complex. The five RecA protomers are coloured as the first five protomers of Fig. 1a. The primary (dT)[15] strand (red) has 13 ordered nucleotides, and the complementary (dA)[12] strand (magenta) has 10 ordered nucleotides. b, View of the heteroduplex looking down the filament axis, showing the three central base-pair triplets (of RecA^2, RecA^3 and RecA^4).
