Sigma factor vs DNA-directed RNA pol

Some cluster A phages contain a sigma factor that is mislabeled as "DNA directed RNA polymerase". This is due to a misinterpretation of a PDB crystal structure comprised of a complex of proteins. The gene in question aligns to the sigma factor in the complex, not the RNA pol. At this time, no cluster A phages contain a verifiable RNA polymerase. |

If you are unsure of how to call the sigma factor, we recommend not calling it as such, instead use DNA binding protein. |
