S. pneumoniae MurC Assay Kit Plus-100

Mfr.No.	MURC100KN
Description	MurC or UDP-N-acetylmuramic acid:L-alanine ligase is the first of four paralogous amino acidadding enzymes in the pathway of peptidoglycan biosynthesis in bacteria. It is an essential enzyme and attractive target for anti-bacterial drug discovery. MurC catalyzes the addition of L-alanine onto the nucleotide precursor UDP-MurNAc generating UDP-MurNAc-L-Ala. The ligation reaction is coupled to the hydrolysis of ATP forming ADP and inorganic phosphate. The S. pneumoniae MurC Assay is based on measurement of the inorganic phosphate generated from the MurC reaction. The inorganic phosphate is detected by light absorbance at 650 nm. The assay reactions and detection can be performed by using 384-well or 96-well assay plates. Alternatively, the assay reaction can be carried out in Eppendorf tubes and the signal is measured using a cuvette if a plate reader is not available. The high throughput assay can be used for screening inhibitors of E.coli MurC in drug discovery research. It may also be used for characterization of E.coli MurC.

Protocols Description	ASSAY PROTOCOL The following assay protocol is based on the 384-well plate assay format. The reaction volume is 30 µl and the final assay volume is 75 µl. For 96-well plate assays, the reaction volume is 60 µl and the final assay volume is 150 µl. For detection using a cuvette, the reaction volume is 400 µl and the final assay volume is 1000 µl. 1.Reagent preparation: For each 10 assay reactions, (1) Prepare 297 µl of premix composed of 261 µl of H2O, 33 µl of 10 x Buffer and 3.3 µl of 100 x S. pneumoniae MurC. (2) Prepare 33 µl of 10 x Enzyme substrate by mixing 3.3 µl of 100 x UDP-MurNAc, 3.3 µl of 100 x L-Ala, 3.3 µl of 100 x ATP, and 23.1 µl of water. 2. Reaction: Mix 27 µl of the premix with 3 µl of the 10 x Enzyme substrate in each well. Incubate the reaction mixture at 37°C for 60 min. 3. Detection: Add 45 µl of the Dye MPA3000 into the 30 µl of the reaction mixture. Incubate for 5 min. Measure the light absorbance at 650 nm.
