In crude extracts. Total protein was isolated from cultures grown to an OD600 of 0.5, 1.0 and centrifuged for 5 min at 12,000 g. The aque2.0 of your strains wildtype (s4197), bglJ constitutive (bglJC, T1030), leuO constitutive (leuOC, ous phases have been extracted once more with hot pheT1146) and hns (T223). eighty g of crude protein extract have been separated on a 12 sDspAGe and transferred to nitrocellulose membrane by electrotransfer. casc was immunodenol, followed by an extraction with phenol/ tected by the anticascade serum raised in rabbits. Lane 9 shows the separation of 500 ng chloroform. Following precipitation with ethanol, purified cascadecas3. Lane 14 shows molecular weight marker. the pellets have been dissolved in TE buffer (ten mM TRISHCl pH 7.5, 1 mM EDTA) and incurevealed that all cas genes located on the polycistronic mRNA bated with 20 units of RNasefree DNaseI (Roche) for 1 h at are represented to virtually equal amounts in leuOC and bglJC 37 . The mixtures have been once more extracted with phenol/chlorostrains, at least beneath steadystate growth situations. Consequently, type and precipitated with ethanol. Lastly, the pellets have been disit is tempting to speculate that the reduction of Cascade con solved in TE buffer along with the RNA yields have been determined by UV centration in bglJC cells may well be a consequence of a reduced spectroscopy. The excellent with the RNA preparation was verified stability or assembly with the Cascade complex. The sort IE on agarose gels. Cascade complex of E. coli K12 contains 11 protein subunits RNA stability assay with rifampicin. E. coli cultures had been composed of nonstoichiometric amounts in the 5 Cas pro grown to an OD600 two.0 and treated with 500 gml1 rifampiteins CasABCDE (CasA1B2C6D1E1).14,15 The reduction of your cin (AppliChem). 5 ml aliquots have been taken at indicated time Cascade concentration in bglJC cells may perhaps be brought on by aber points and straight away mixed with one particular volume hot phenol. The rant folding in the person subunits or misassembly on the extraction of total RNA was performed as described above. complicated, major for the degradation of specific Cascade proPrimer extension analysis. Indicated amounts of the total teins. Certainly, the stability from the Cas3 protein has been shown RNA samples had been annealed to 0.5 pmol of 5’32Plabeled oligoto rely on the presence with the heatshock chaperone HtpG nucleotides.
