Identification and analysis of hepatitis C virus NS3 helicase inhibitors using nucleic acid binding assays
Typical assays used to discover and analyze small molecules that inhibit the hepatitis C virus (HCV) NS3 helicase yield few hits and are often confounded by compound interference. Oligonucleotide binding assays are examined here as an alternative. After comparing fluorescence polarization (FP), homogeneous time-resolved fluorescence (HTRF®; Cisbio) and AlphaScreen® (Perkin Elmer) assays, an FP-...
متن کاملUse of a restriction enzyme-digested PCR product as substrate for helicase assays
DNA helicases play essential roles in many cellular processes. The currently available techniques to generate substrates for helicase assays are fairly complicated and need some expertise not available in all laboratories. Here, a PCR-based method to generate a substrate for a helicase assay is described, and its application for several archaeal, bacterial and viral enzymes is demonstrated.
متن کاملChallenges of PTH Assays
Parathyroid hormone (PTH) plays a vital role in regulating of blood Calcium. In addition, it regulates the amount of phosphate and vitamin D in the blood. PTH is a polypeptide hormone that found in the blood circulation as peptides with different amino acid counts. The active form of the PTH which has biological activity, contains 84 amino acids, but under the influence of proteolytic enzymes...
متن کاملUvrD helicase
In classical bacterial nucleotide excision repair (NER), a bulky DNA lesion such as a UV photoproduct is recognized by the UvrAB DNA damage recognition complex, and the strand containing the adduct is incised by UvrC nuclease upstream and downstream of the lesion. UvrD helicase subsequently loads at a nicked DNA site and unwinds the 12-base pair duplex containing the lesion, thereby creating a ...
متن کاملFluorescent single-stranded DNA binding protein as a probe for sensitive, real-time assays of helicase activity.
The formation and maintenance of single-stranded DNA (ssDNA) are essential parts of many processes involving DNA. For example, strand separation of double-stranded DNA (dsDNA) is catalyzed by helicases, and this exposure of the bases on the DNA allows further processing, such as replication, recombination, or repair. Assays of helicase activity and probes for their mechanism are essential for u...
