Competitions were carried out with a 100-fold excess of either repressor fragment (rep, lane 2 ), Eco RI– Bgl II fragment containing the 5′ activator in sense orientation (5′/act-s, lane 3), or the same Eco RI– Bgl II fragment in antisense orientation (5′/act-as, lane 4 ). Immunoprecipitation of proteins UV cross-linked to radiolabeled repressor fragment (lane 5 ) by anti-Bruno antiserum (lane 6 ) or preimmune serum (lane 7 ). Simultaneous binding of p50 and Bruno was tested by treating with <t>RNase</t> A only after the immunoprecipitation. (Lane 8 ) Anti-Bruno antiserum; (lane 9 ) preimmune serum. We noted that in some cases (as shown here) the intensity of the upper band of the p50 doublet was reduced after coprecipitation. The locations of the 5′ and 3′ competitors in the osk transcript are indicated below. The radiolabeled probe is indicated by an asterisk. The reverse experiment, with activator element RNA as a radioactive probe, and cold activator and repressor RNA elements as unlabeled competitors, yielded the same result with respect to p50 (data not shown).

    CID-MS/MS spectrum of [AUUUAm 2 G] 2− derived from RNase T1 digestion of yeast tRNA Phe−1 . The doubly charged ion with m / z = 966.6 was analyzed by CID. The nucleotide sequence was verified by manual interpretation of the a- and c-type (normal text) and w - and y -type ( italic text ) product ion series as indicated in the figure. The parent ion losing methyl guanine [P−B(mG) 2− ], the parent ion losing adenine [P−B(A) 2− ], the y5 ion losing methyl guanine [y5−B(mG) 2− ], the y5 ion losing adenine [y5−B(A) 2− ], y5 2− and c5 2− were doubly charged products. All other assigned signals were singly charged products, unless indicated otherwise. The asterisks indicate hydrated or dehydrated ions of a-, c-, w- or y-type products.
