Fluorescent Probe Compound for Enzyme Detection and Isolation

The patent employs fluorescence dyes as indicator components that undergo color/fluorescence changes when bound to enzymes or involved in enzymatic reactions. This optical signal change enables highly sensitive detection of enzyme-substrate interactions, overcoming the low detection sensitivity of conventional microarrays. The fluorescence signal provides clear, reliable identification that is not compromised by contaminants.

The probe compound acts as an intermediary molecule that bridges the gap between enzymes and detection systems. It comprises a test component (substrate or metabolite) and an indicator component (fluorescence dye), where the indicator serves as a mediator to translate enzymatic activity into a detectable signal. This intermediary approach enables sensitive and reliable detection without direct interaction between contaminants and the detection system.

The patent replaces sequence-based bioinformatic analysis with a direct experimental approach using probe compounds. Instead of relying on computational predictions from genome sequences (which suffer from high error rates and missing annotations), the method directly detects enzymatic activities through fluorescence signals. This substitution of indirect sequence-based inference with direct functional measurement eliminates the need for questionable annotations and provides reliable functional assignments.

The probe compound system enables self-service functional annotation by directly measuring enzyme activities without requiring prior sequence information or database annotations. The method allows organisms or communities to annotate themselves through their actual metabolic reactions, independent of existing genomic knowledge. This self-service approach discovers functional information that sequence-based methods miss entirely.
