histone deacetylase 1/Histone deacetylase 1 in Human (target type: SINGLE PROTEIN) [ChEMBL: CHEMBL325] [GtoPdb: 2658] [UniProtKB: Q13547]
ChEMBL	Enzyme Assay: Compounds for testing were diluted in DMSO to 50 fold the final concentration and a ten point three fold dilution series was made. The compounds were diluted in assay buffer (50 mM HEPES, pH 7.4, 100 mM KCl, 0.001% Tween-20, 0.05% BSA, 20 uM TCEP) to 6 fold their final concentration. The HDAC enzymes (purchased from BPS Biosciences) were diluted to 1.5 fold their final concentration in assay buffer. The tripeptide substrate and trypsin at 0.05 uM final concentration were diluted in assay buffer at 6 fold their final concentration. The final enzyme concentrations used in these assays were 3.3 ng/ml (HDAC1), 0.2 ng/ml (HDAC2), 0.08 ng/ml (HDAC3) and 2 ng/ml (HDAC6). The final substrate concentrations used were 16 uM (HDAC1), 10 uM (HDAC2), 17 uM (HDAC3) and 14 uM (HDAC6). Five ul of compounds and 20 ul of enzyme were added to wells of a black, opaque 384 well plate in duplicate. Enzyme and compound were incubated together at room temperature.
