Supplementary Figure 7: Comparison of the fingers–palm domain of LtrA with that of TERT and Prp8.
From: Structure of a group II intron in complex with its reverse transcriptase
(a) Docking of fingers-palm domain of TERT (PDB code: 3DU6; left panel) and Prp8 (PDB code: 3JB9; right panel) into the cryo-EM density corresponding to the LtrA fingers-palm domain. (b) Structure superimposition of LtrA fingers-palm domains with corresponding domains from TERT (left panel) and Prp8 (right panel) show the RMSD values of 2.0 Å and 2.7 Å, respectively. (c) Rigid-body docking of TERT (left panel) and Prp8 (right panel) fingers domain onto group IIA intron shows a significant steric clash between Prp8 and intron domain Id(iii)a.
