In vitro binding assay for RbgA mutants to 50S subunit under different nucleotide conditions. Purified RbgA-his6 or RbgA mutant-his6 (50 nM) was incubated with purified 50S (10 nM) subunit and GDP, GTP or GMP-PNP (400 µM) at 37°C. The presence of RbgA was tested by western blot with custom RbgA-antibody and quantified. Percentages were generated by assigning RbgA + 50S + GMP-PNP as 100%. Lane 1: RbgA + 50S + GDP; lane 2: RbgA + 50S + GTP; lane 3: RbgA + 50S + GMP-PNP; lane 4: A206D + 50S + GDP; lane 5: A206D + 50S + GTP; lane 6: A206D + 50S + GMP-PNP; lane 7: Y225A + 50S + GDP; lane 8: Y225A + 50S + GTP; lane 9: Y225A + 50S + GMP-PNP.
