| Description: | Assay A, a 384-well format on a Corning 3653 assay plate is used, and monitored by UV-vis spectroscopy in continuous mode at rt. Compounds were prepared in DMSO as 4 mM stocks, diluted using an 11-point half-log scheme on a Biomek FX (Beckman Coulter), and incubated at rt for 30 minutes with the reaction mixture containing 50 mM HEPES, pH 7.4, 140 mM KCl, 3.5 mM MgCl2, 0.8 mM fructose, 2 mM TCEP, 0.8 mM PEP, 0.7 mM NADH, 0.01% Triton X-100, 30 U/mL pyruvate kinase-lactate dehydrogenase, and 10 nM purified KHK-C. The compound concentration in each well ranged from 1 nM to 100 μM. The reaction was initiated with the addition of 0.2 mM ATP. The absorbance was measured for 30 minutes on a SpectraMax reader (Molecular Devices) after ATP was added. The concentrations provided are based on the final mixture volume of 40 μL (referred to as the final concentration). |
