Murd Ligase

A novel assay for monitoring the activity of the bacterial enzyme UDP- N-acetylmuramyl-L-alanine:D-glutamate ligase (MurD ligase) is presented. MurD, which belongs to an enzyme family of Mur ligases, is essential for the synthesis of bacterial peptidoglycan and therefore represents an attractive target for the discovery of novel antibacterial agents. The inhibition assay described in this article is amenable to high-throughput screening. It is based on the detection of the accumulation of adenosine 5′-diphosphate (ADP), a product of the reaction catalyzed by MurD ligase, by conversion to a fluorescent signal via a coupled enzyme system, using the ADP Quest™ assay kit from DiscoveRx. The novel assay has been validated by obtaining KM,app values for substrates D-Glu, UDP- N-acetylmuramyl-L-alanine (UMA) and ATP that are in agreement with the data reported in the literature. A counterscreen assay was introduced to eliminate false positives, and some of the known MurD inhibitors have been retested to compare the data measured with different methods. Moreover, a focused library of around 1000 compounds was screened for the inhibition of MurD to assess the performance and robustness of the assay. Finally, a novel MurD inhibitor belonging to a new structural class, with an IC50 value of 105 µM, was discovered. ( Journal of Biomolecular Screening 2009:412-418)

ABSTRACT Current assays for screening new antimalarials need initiators of β-hematin formation that require laborious preparation, special devices, and substrates. In this study, based on reduction of heme absorption in β-hematin formation, we developed a simple colorimetric assay using Tween 20 as an initiator and a microplate reader for high-throughput screening of inhibitors of β-hematin formation.
