Structure of Thermus Thermophilus Cse3 bound to an RNA representing a product complex

The structure was published by Gesner, E.M., Schellenberg, M.J., Garside, E.L., George, M.M., and Macmillan, A.M., in 2011 in a paper entitled "Recognition and maturation of effector RNAs in a CRISPR interference pathway." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 3.099 Å and deposited in 2011.

The experimental data on which the structure is based was also deposited.

This PDB entry contains a complex of 2 biomacromolecules, namely Putative uncharacterized protein TTHB192 and RNA (5'-R(*GP*UP*CP*CP*CP*CP*AP*CP*GP*CP*GP*UP*GP*UP*GP*GP*GP*(23G))-3').
