Solution structure of NusA-NTDΔ.
(a) Structural ensemble of the 20 accepted lowest energy structures in ribbon representation colored according to secondary structure (α-helices, blue; β-strands, green; loops, grey). (b) Cartoon representation of the calculated structure with the lowest energy. Secondary structure elements are colored as in (a) and labeled. Helix α4 is highlighted in purple, the head and body parts are indicated.
