Target: Acetyl-CoA carboxylase 2 (SINGLE PROTEIN), Homo sapiens
UniProt: O00763
Assay: Spectrophotometric 384 Well Assay: Malonyl CoA formation by acetyl CoA carboxylases is stoichometrically linked to the consumption of ATP. ACC2 activity is measured in a NADH-linked kinetic method measuring ADP generated during the ACC reaction using a coupled lactate dehydrogenase/pyruvate kinase reaction.For biological testing, a human ACC2 construct which lacks the 128 amino acids at the N-terminus for increased solubility (nt 385-6966 in Genbank entry AJ575592) is cloned. The protein is then expressed in insect cells using a baculoviral expression system. Protein purification is performed by anion exchange.All compounds are dissolved in dimethyl sulfoxide (DMSO) to a concentration of 10 mM.Assay reactions are then carried out in 384-well plates, with hACC2 in an appropriate dilution and at final assay concentrations (f.c.) of 100 mM Tris (pH 7.5), 10 mM trisodium citrate, 25 mM KHCO3, 10 mM MgCl2, 0.5 mg/ml BSA, 3.75 mM reduced L-glutathione, 15 U/ml lactate dehydrogenase, 0.5 mM phosphoenolpyruvate.

To prepare the compound for the assay, dissolve it in either DMSO or, if cyclization is suspected, in pH 2.0 water (0.01 N HCl) to a final concentration of 100 mM. For pH 2.0 stocks, incubate at room temperature for a minimum of four hours and up to overnight. From this, prepare a 1 mM stock at pH 7.4 in 50 mM Tris. If the inhibitor is insoluble at this concentration, dilute the 100 mM stock 1:10 to 10 mM. Using this stock, prepare a 0.1 mM stock as described above.2. Prepare a dilution plate for the compound stocks to be tested. Add the 0.1 and/or 1 mM stocks prepared previously to row A of a 96-well plate. From this, perform 1:10 serial dilutions into the appropriate assay buffer down the columns as shown below:3. Prepare 20× substrate solution by diluting the DMSO stocks into the appropriate assay buffer.4. Dilute the enzymes into their appropriate assay buffers. The dilution factor is lot dependent and must be determined prior to performing the assay. The final enzyme concentrations should be 0.1, 0.8, 0.4, 0.2, 1.2, and 0.6 nM for DPPIV, 8, 9, II, FAP and PREP respectively. Add 180 μL to each well needed in columns 2-10.5. Add 20 μL of the compound of interest from the dilution plate prepared in step 2 to columns 2-10 of the assay plate where appropriate. Each sample should be tested in triplicate.

A 10 μL sample of this solution is then added to 990 μL of pH 8 buffer (0.1 M HEPES, 0.14 M NaCl), and the solution is allowed to stand at room temperature overnight.The enzyme solution is prepared by diluting 20 μL of DPIV (concentration 2.5 nM) into 40 mL of pH 8 buffer.The substrate solution is prepared by dissolving 2.0 mg of L-alanyl-L-proline-para-nitroanilide into 20 mL of pH 8 buffer.250 μL of enzyme solution is added to well #B1 to #H1, #A2 to #H2, and #A3 to #H3 of a 96 well plate, while well #A1 receives 250 μL of pH 8 buffer instead of enzyme solution. 904 of pH 8 buffer is then added to column 5 (from well #A5 to #H5).
