Screening Diverse Glycosyltransferases Using Homogenous, Fluorescent Transcreener HTS Assays for Direct Detection of Nucleotide Products

24 Nov 2014

Glycosyltransferase enzymes participate in extremely diverse metabolic and regulatory roles by catalyzing the transfer of sugar molecules to protein, lipid and carbohydrate acceptors as well as endogenous and xenobiotic small molecules. From a drug discovery point of view, they are gaining increasing interest as targets for “substrate reduction therapy” in lysosomal storage diseases, and as anti-microbial targets for disrupting bacterial cell wall biosynthesis. This study indicates that a suite of Transcreener assays may be a powerful approach for screening and profiling diverse glycosyltransferases in humans.

Transcreener® UDP² Glycosyltransferase Assays

BellBrook Labs

The Transcreener® UDP² Glycosyltransferase Assay Kit directly detects UDP—the conserved product of glycosyltransferase reactions—in a homogeneous mix-and-read format. Compatible with FP, FI, and TR‑FRET readouts, it supports UDP concentrations from 1–250 µM and delivers exceptional HTS performance (Z’ ≥ 0.7) across 96-, 384-, and 1536‑well formats.

Transcreener® AMP²/GMP² Phosphodiesterase Assays

BellBrook Labs

The Transcreener® AMP²/GMP² Phosphodiesterase Assay Kit directly detects AMP or GMP produced by PDEs, ligases, synthetases, ENPP1, and related enzymes using a mix‑and‑read FP or TR‑FRET format—no coupling steps needed. Compatible with 1–1000 µM native substrates, it delivers excellent HTS performance (Z’ ≥ 0.7, ≥100 mP shift) in a one-step, far‑red fluorescence assay.

Transcreener® GDP GTPase Assays

BellBrook Labs

The Transcreener® GDP GTPase Assay Kit directly measures GDP produced during GTP hydrolysis in a homogeneous mix‑and‑read format—no coupling enzymes needed. Compatible with GTPases, GAPs, and GEFs, it supports FP, FI, and TR‑FRET readouts using far‑red tracers to reduce interference. HTS‑ready with excellent sensitivity (Z′ ≥ 0.7), it streamlines screening and profiling workflows.
