Summary
| Editing Factor: | EMP9 |
| Synonym: | Empty Pericarp 9; GROWING SLOWLY 1; GRS1 |
| Description: | Deletions of two N-terminal PPR motifs and partial E+ domain do not eliminate the editing function of EMP9; Loss of EMP9 function abolishes the C-to-U editing of ccmB-43 and rps4-335 sites in mitochondria; The loss of editing at ccmB-43 and rps4-335 affects the maturation of cytochrome c and impairs the biogenesis of mitochondrial respiratory complexes, particularly complex III |
| Protein Family: | Pentatricopeptide repeat (PPR) protein |
| Subclass: | E+ |
| Physical Interaction: | NA |
| Construct Structure: | PLS-E1-E2-E+ |
| Gene ID & Species: | AT4G32430 (Arabidopsis thaliana) |
| Edited Gene(s): | rps4 |
| Editing Type(s): | C-to-U (4) |
