RSV stocks were resuspended in HBSS containing 0.5% bovine serum albumin and 100 mM magnesium sulfate and frozen at -70° C.
There are two homologous type IA topoisomerases present in E. coli . Topoisomerase III has potent DNA decatenating activity for resolution of plasmid DNA replication intermediates, but much weaker relaxation activity than topoisomerase I [ 17 ] . To exhibit maximal relaxation activity, topoisomerase III requires high temperature (52°C) along with low magnesium and monovalent ion [ 17 18 ] . In contrast, E. coli topoisomerase I was not active in the in vitro assay for resolution of plasmid DNA replication intermediates [ 19 ] . Removal of the C-terminal 49 amino acids from the 653 amino acid topoisomerase III protein resulted in drastic reduction of catalytic activity [ 20 ] . Fusion of the carboxyl-terminal 312 amino acid residues of E. coli topoisomerase I, which includes the entire ZD domain, onto the 605 N-terminal amino acids of topoisomerase III generated a hybrid topoisomerase that has relaxation activity resembling topoisomerase III along with weak decatenating activity [ 21 ] . Although preferring single-stranded DNA as binding substrate, topoisomerase I had been shown to also bind double-stranded DNA [ 22 ] , but there is no data available to indicate which domain in the enzyme is responsible for this interaction.
For example, the junction between the aptamer and the Group I ribozyme in the aptazyme Th2P6 resembled the deletion variant td ΔP6-6; the aptazyme was activated by theophylline, while the splicing defect of the deletion variant at 3 mM magnesium was suppressed by 8 mM magnesium or by stabilization of a tetraloop sequence that capped the P6 helix [ 15 ] . Defects that poise a ribozyme between active and inactive conformers have previously been used to engineer effector-dependence [ 20 ] .
, magnesium or buffering agents) will reduce the amount of limestone needed.
Polyvinylpyrrolidone (PVP), Tween-20R™, phosphate-buffered saline (PBS), and Dulbecco's phosphate-buffered saline (containing no calcium or magnesium) were purchased from Sigma Chemical Co. (St.
