Had been also sensitive to 1-10-phenanthroline. (B) Screen from the effect of pH on proteolytic activity in YNB and DMEM supernatants. 3 efficiently cleaved IQ substrates have been chosen for this analysis. The activity scale is differs for this experiment because this assay was performed on a SpectraMax Gemini plate reader (Molecular Devices) although situations have been otherwise equivalent. Averages and S.D. are shown for triplicates. (PDF) S2 Fig. Reproducibility of MSP-MS assay. (A) YNB media conditioned by wild form C. neoformans was incubated with all the 228-member MSP-MS peptide library for 15, 60, 240, and 1200 minutes. The amount of cleavage internet sites was assessed at each and every time point, in triplicate. Error bars represent S.D.

(A) Proteolysis of IQ-2 was measured within a fluorogenic assay of YNB supernatants from all peptidase deletion strains. Deletion of MAY1 led to complete loss of cleavage of IQ-2. Columns represent imply S.D. (B) May1 was diluted to 14.6 nM in 100 mM MES pH 4.five, 100 mM NaCl and incubated with IQ-2. In the get started of the reaction and after 24 hours of incubation at space temperature, samples had been collected and analyzed by Matrix Assisted Laser Desorption Ionization-Time of Flight (MALDI-TOF). Determined by evaluation of its substrate specificity, it was hypothesized that May1 would cleave amongst the phenylalanine and leucine in IQ-2. The sodium adduct was observed for the N-terminal fragment of your expected cleavage item, confirming the site of cleavage.
