Structure ID: 4RZD

Chain: A

Description: crystal structure of a preq1 riboswitch. note that due to crystal packing there is no intramolecular l4-rbs pseudoknot formation in the 4rzd structure, instead there is an intermolecular l4-rbs interaction (liberman et. al doi:10.1073/pnas.1503955112).

Experimental method: x-ray diffraction

Resolution: 2.75
