P. falciparum cell lysate was functionally screened for deNeddylases using FLAG-HsNedd8-VS or FLAG-PfNedd8-Prg, the latter was performed twice (FLAG-PfNedd8-Prg_1 and FLAG-PfNedd8-Prg_2). Reactions were followed by anti-FLAG immunoprecipitation and proteomic analysis of bound enzymes. Enzymes were individually expressed in E.coli, purified, and their specificity was validated by reacting with Ub-AMC, HsNedd8-AMC and PfNedd8-AMC.
