Summary
| Editing Factor: | YS1 |
| Synonym: | YELLOW SEEDLING 1 |
| Description: | YS1 is absolutely required for editing of site 25992 in rpoB transcripts encoding the beta subunit of the plastid-encoded RNA polymerase (PEP); The activity of PEP containing RpoB translated from unedited transcripts is insufficient to support rapid chloroplast differentiation |
| Protein Family: | Pentatricopeptide repeat (PPR) protein |
| Subclass: | DYW |
| Physical Interaction: | NA |
| Construct Structure: | PLS-E-DYW |
| Gene ID & Species: | AT3G22690 (Arabidopsis thaliana) |
| Edited Gene(s): | rpoB |
| Editing Type(s): | C-to-U (9) |
| Publication(s): |
