| + | == Function == | ||
| + | [https://www.uniprot.org/uniprot/RPA49_YEAST RPA49_YEAST] DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Component of RNA polymerase I which synthesizes ribosomal RNA precursors. A49 is easily dissociated from the rest of pol A (pol I), producing the form A*, which shows impaired transcriptional activity and increased sensitivity to alpha-amanitin. The function of A49 might be linked to the RNase H activity that was found associated with this subunit. | ||
