| Popis: | In vitro chromatin protein phosphorylation is enhanced in chromatin isolated from gibberellin-treated maize seedlings, as compared with chromatin from control plants. Studies of the influence of gibberellin on the template activity of maize chromatin, using homologous RNA polymerase II, showed that polymerase contains a factor dissociating in 0.35 M (NH4)2SO4, which is decisive of the enzyme specificity. It was found that at this ionic strength protein kinase was removed from RNA polymerase. A role for protein kinase as a RNA polymerase II subunit, responsible for the specificity of transcriptase, is postulated. |
