Summary
| Editing Factor: | CRR4 |
| Synonym: | CHLORORESPIRATORY REDUCTION 4; ATCRR4 |
| Description: | The heterogous complementation of Arabidopsis crr4-3 mutant, in which RNA editing of ndhD-1 is completely impaired, with CRR4 orthologous genes derived from Nicotiana species suggested that the reduction in editing efficiency in N. tomentosiformis is caused by amino acid variations accumulating in CRR4 |
| Protein Family: | Pentatricopeptide repeat (PPR) protein |
| Subclass: | E+ |
| Physical Interaction: | NA |
| Construct Structure: | PLS-E-E+ |
| Gene ID & Species: | NA (Nicotiana tabacum) |
| Edited Gene(s): | ndhD |
| Editing Type(s): | C-to-U (1) |
