Abstract

We have studied the effect of protein phosphokinase (EC 2.7.1.37; ATP:protein phosphotransferase) and phosphoprotein phosphatase (EC 3.1.3.16; phosphoprotein phosphohydrolase) on reverse transcriptase (RNA-dependent DNA nucleotidyltransferase) activity of Rous sarcoma virus. Protein kinase from Rous sarcoma virus-transformed chick embryo fibroblasts was purified by DEAE-cellulose chromatography, Sephadex gel filtration, and isoelectric focusing. Purified reverse transcriptase from Rouse sarcoma virus was preincubated with protein kinase and ATP under conditions allowing incorporation of phosphate into substrate protein. After the preincubation, reverse transcriptase activity was assayed in the presence of poly(rA).oligo(dT) as template. A 2- to 5-fold increase of reverse transcriptase activity was found after the preincubation of reverse transcriptase with protein kinase and ATP. Incubation of reverse transcriptase with heat-treated, inactive protein kinase and ATP had no effect on transcriptase activity. When the transcriptase preparation was incubated with protein kinase and [gamma-32P]ATP and subsequently purified by chromatography on phosphocellulose and Sephadex gel filtration, significant amounts of 32P-labeled proteins were found in the fractions exhibiting reverse transcriptase activity, suggesting 32P incorporation into transcriptase or transcriptase-associated proteins. A 20-60% decrease of reverse transcriptase activity was observed after incubation of reverse transcriptase with phosphatase. The results suggest that phosphorylative modification of reverse transcriptase may be critical in the regulation of reverse transcriptase-catalyzed DNA synthesis

Abstract

Thus far, conventional biophysical techniques, such as NMR spectroscopy or X-ray crystallography, allow the determination, at atomic resolution, of only structural domains of large RNA molecules such as group I introns. Determination of their overall spatial organization thus still relies on modeling. This requires that a relatively high number of tertiary interactions are defined in order to get sufficient topological constraints. Here, we report the use of a modification interference assay to identify structural elements involved in interdomain interactions. We used this technique, in a group II intron, to identify the elements involved in the interactions between domain V and the rest of the molecule. Domain V contains many of the active site components of these ribozymes. In addition to a previously identified 11 nucleotide motif involved in the binding of the domain V terminal GAAA tetraloop, a small number of elements were shown to be essential for domain V binding. In particular, we show that domain III is specifically required for the interaction with sequences encompassing the conserved 2 nucleotide bulge of domain V.
