Figure 5From: Finding of widespread viral and bacterial revolution dsDNA translocation motors distinct from rotation motors by channel chirality and sizeChirality comparison of revolution and rotation motors. (A) In revolution motors, the right-handed DNA revolves within a left-handed channel, such as in the connector channels of bacteriophage Phi29 [46], P22 [45], and SPP1 [65]. (B) In rotation motors, the right-handed DNA rotates through a right-handed channel via the parallel thread, with RecA [76], DnaB [69] and E1 helicase [79] shown as examples. For E1 helicase, only the inside right-handed hairpin staircases that traces along the ssDNA are shown.Back to article page
