Drug Target Assay Kit

MurD is the D-glutamic acid-adding enzyme of bacterial cell wall peptidoglycan synthesis. It adds D-glutamic acid to UDP-MurNAc-L-Ala to form UDP-MurNAc-dipeptide, using ATP hydrolysis that releases ADP and inorganic phosphate. It is essential and an attractive antibacterial drug target.

Pack Sizes

Both sizes include the E. coli MurD enzyme. The only difference is the number of assays: MURD100KE is for 100 assays and MURD500KE for 500 assays (384-well format), with component volumes scaled.

100 assays (MURD100KE) 100 assays; enzyme included
500 assays (MURD500KE) 500 assays; enzyme included

Kit Components

Component 100 assays (MURD100KE) 500 assays (MURD500KE)
10 x Buffer 400 µl 2 ml
100 x UDP-MurNAc-L-Ala (UMA) 35 µl 170 µl
100 x D-Glu 35 µl 170 µl
100 x ATP 35 µl 170 µl
100 x E. coli MurD (2000 nM) 35 µl 170 µl
Phosphate detection dye (also sold separately as MicroMolar Phosphate Assay Reagent, BHT16300173) 5 ml 25 ml

Assay Principle

The kit measures the inorganic phosphate released when MurD adds D-glutamic acid to UDP-MurNAc-L-Ala and hydrolyzes ATP with a phosphate detection dye; absorbance at 650 nm is proportional to MurD activity, so inhibitors reduce the signal.

Q.What does this kit measure?
A.It measures the activity of E. coli MurD by detecting the inorganic phosphate released when MurD adds D-glutamic acid to UDP-MurNAc-L-Ala and hydrolyzes ATP. It is used to screen inhibitors of this bacterial cell wall enzyme and to characterize the enzyme.
Q.What is the difference between the options?
A.Both sizes include the E. coli MurD enzyme. The only difference is the number of assays: MURD100KE is for 100 assays and MURD500KE for 500 assays (384-well format), with component volumes scaled.
Q.Is a protocol available?
A.Yes. The manufacturer's protocol (E. coli MurD Assay, linked under Documents) covers catalog # MURD100KE, MURD500KE.
Q.How long does the assay take?
A.About 65 min (60 min reaction + 5 min detection). See the protocol for the exact steps.
Q.How should the kit be stored?
A.The E. coli MurD Assay Kit Plus is shipped frozen. Please contact us for long-term storage conditions.
