| pubmed-article:6153531 | pubmed:abstractText | A non-steady-state kinetic method has been developed to observe the initiation of long RNA chains by Escherichia coli RNA polymerase without the enzyme turnover. This method was used to determine the order of binding of the first two nucleotides to the enzyme in RNA synthesis with the first two nucleotides to the enzyme in RNA synthesis with poly(dA-dT) as the template. It was shown that initiator [ATP, uridyly(3'-5')adenosine, or adenyly(3'-5')uridylyl-(3'-5')adenosine] binds first to the enzyme-template complex, followed by UTP binding. The concentration dependence of UTP incorporation into the initiation complex suggests that more than one UTP molecule may bind to the enzyme-DNA complex during the initiation process. Comparison of the kinetic parameters derived from these studies with those obtained under steady-state conditions indicates that the steps involving binding of initiator or UTP during initiation cannot be rate limiting in the poly(dA-dT)-directed RNA synthesis. The non-steady-state technique also provides a method for active-site titration of RNA polymerase. The results show that only 36 +/- 9% of the enzyme molecules are active in a RNA polymerase preparation of high purity and specific activity. In addition, the minimal length of poly(dA-dT) involved in RNA synthesis by one RNA polymerase molecule was estimated to be approximately 500 base pairs. | lld:pubmed |
