Analysis of the heterogenous structural states of the hexameric ATPase PilU of the Type IV pili from Vibrio cholerae

Yirui Guo, Shantanu P. Shukla, G. Minasov…·K.J.F. Satchell

The paper determines six structural states of PilU, a retraction ATPase, revealing its homohexameric assembly and conformational flexibility, which may explain its weak ATPase activity and dependence on PilT.

Translational T-box riboswitches bind tRNA by modulating conformational flexibility

Eduardo Campos-Chavez, Sneha Paul, Zunwu Zhou…·Alfonso Mondragón

This study uses single-molecule FRET to analyze the binding mechanism of the Mycobacterium tuberculosis IleS T-box riboswitch, revealing a two-step model and the role of specific sequences in conformational flexibility and tRNA recognition.
