Main description This dataset depicts the catalysis of L-cysteine to sulfur by the desulfurase IscS in the presence of the scaffold protein IscU. This kinetic system was described in the PhD thesis "New tools for enzymatic characterization and inhibitor screening: post-Michaelis-Menten kinetic analysis" by Maria Filipa Pinto (https://hdl.handle.net/10216/126202), and this dataset was then used as a study case for the webserver interferENZY (a web-based tool for enzymatic assay validation and standardized kinetic analysis; visit https://interferenzy.i3s.up.pt for more information). To this end, it was converted to the format here presented: tab-separated *.txt input required for interferENZY analysis. Dataset organization Line 1: Tab-separated initial concentrations of substrate L-cysteine in micromolar (µM) concentration Line 2: Concentration of enzyme (1 µM) Line 3: Units of time Line 4: Units of concentration for substrate values and measurements Line 5: Dataset name Line 6 and downwards: Tab-separated column-pairs of the progress curves (time,Product) corresponding to the indicated values of initial concentrations of substrate in line 1 Contact information: Maria Filipa Pinto (mfpinto@i3s.up.pt) Pedro M.
