The peak fractions of the heparin-Sepharose CL-6B column were analyzed by SDS-PAGE and visualized by Coomassie Brilliant Blue staining (top panel) or immunoblotting with monoclonal anti-polyhistidine antibody (bottom panel). 400 and 50 ng of protein were loaded for the top and bottom panels, respectively. Lane 1, wild-type CEL-1-(13–221); lane 2, C136S; lane 3, R142K; lane 4, D76N; lane 5, E111Q; lane 6, D112N. For reasons that are not clear, the D76N mutant shows slightly altered mobility. B, RTPase assay. The wild-type and mutated CEL-1-(13–221) proteins were incubated at 30 °C for 10 min with 1 M termini of a [-32P]GTP-labeled 65 nucleotide RNA. Reaction mixtures were analyzed by thin layer chromatography (TLC) on polyethyleneimine-cellulose plates. Released phosphate was detected by autoradiography, and radioactive spots were cut out and quantitated by liquid scintillation counting. Relative amounts of released phosphate were plotted versus protein amount. C, in vivo analysis of CEL-1-(13–221) mutants by plasmid shuffling. YSB719 carrying pDB20H-MCE-(211–597) was transformed with the vector pAD5 or derivatives expressing the indicated CEL-1 alleles. Leu His transformants were tested for growth in the presence of 5-FOA.
