| Popis | RNA polymerase is an essential enzyme. RNAP from gram negative bacteria contain two additional subunits. The delta subunit is 173 aminoacids long and comes from Bacillus subtilis. The N terminal domain displays an ordered structure and the C terminal domain appears to be flexible and unstructured. The N terminal domain was solved either with NMR and Xray. The Xray structure showed completely different behaviour in the region corresponding to beta sheets present in NMR structure. In the Xray structure were found nickel ions which may have a significant effect on the folding of the protein. This is a strong proof that some of the proteins can be differently structured in the solution as in the crystalline phase. |
