Figure 7. Structure of eukaryotic Rrp6 and the bacterial homolog RNase D.

Figure 7

A) S. cerevisiae Rrp6 structure (PDB ID = 2HBL). Domains of Rrp6 are NTD (green), EXO (blue), and HRDC (pink). The active site residues (D238, E240, D296, D365, and Y361A) are shown coordinating two manganese ions (blue spheres). B) E. coli RNase D structure (PDB ID = 1YT3). Domains of RNase D are EXO (blue), HRDC1 (pink), and HRDC2 (orange). The active site residues (D28, E30, D85, D155, and Y151) colored green are coordinating two zinc ions (blue spheres).
