FIGURE 9.
Comparison of structural and catalytic residues of HP0892 with those of its structural homologues. Ribbon displays of H. pylori HP0892 (PDB ID 2OTR) (29) (A); H. pylori HP0894 (PDB ID 1Z8M) (40) (B); E. coli YoeB (PDB ID 2A6R) (18) (C); and Streptomyces aureofaciens RNase Sa (PDB ID 1RGE) (41, 42) (D) are shown. The labeled functional or predicted key residues (see “Discussion”) are colored red. The structures were visualized by the program PyMOL (35).
