Figure 4From: Automatic workflow for the classification of local DNA conformationsStructure of a four-way (Holliday) junction in an inverted repeat sequence 1DCW [115]. The backbone between residues A6 and C7 in chains B and D (shown in red) adopts an unusual BI-like conformation 115 with high ϵ (~ 275°) and A-like χ+1 (~ 208°).Back to article page
