Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for analyzing and identifying enzymatic activities, particularly for glycoside hydrolases and transferases, are limited in resolving complex samples and evaluating large numbers of enzymatic reaction products in parallel, necessitating the development of efficient methods for parallel detection and analysis of enzymatic activities in complex biological mixtures.
Innovation Solution
The use of substrate analogs and nanostructure-initiator mass spectrometry (NIMS) for detecting enzymatic activities, where substrates with perfluorinated tags interact with a hydrophobic NIMS chip surface, allowing for the analysis of reaction products and determination of enzyme activity through the ratio of substrate-to-reaction product ions in a mass spectrum.

Engineering Contradiction Analysis
1Productivity
If conventional methods are used to analyze enzymatic activities, then the analysis can be performed, but the ability to resolve complex samples and evaluate large numbers of enzymatic reaction products in parallel is limited
Solution Approach 1:
The method segments the complex sample analysis by using specific substrate analogs with unique identifiers (fluorescent tags, mass tags, or enzymatic substrates) that allow individual enzymatic activities to be distinguished and detected in parallel within the complex mixture, enabling simultaneous evaluation of multiple enzymes without interference
Solution Approach 2:
The patent introduces substrate analogs as intermediary molecules that interact with enzymes to produce detectable signals. These substrate analogs serve as mediators between the enzymes in the complex sample and the detection system, converting enzymatic activities into measurable outputs that can be resolved and quantified in parallel
2Productivity
If conventional analysis methods are used, then enzyme activities can be detected, but the efficiency of parallel detection and analysis of enzymatic activities in complex biological mixtures is insufficient
Solution Approach 1:
The patent employs a universal detection system that can simultaneously detect multiple types of enzymatic activities through a single analytical run. The system uses multiple substrate analogs with different detection markers that can be processed together, allowing one assay to evaluate numerous enzyme activities across different biological samples in parallel
Solution Approach 2:
The method adds detection dimensions by incorporating multiple types of identifiers (fluorescent tags, mass tags, enzymatic substrates) that enable differentiation of enzymatic activities along multiple detection axes, allowing simultaneous quantification of numerous enzymes through multi-dimensional analysis rather than sequential single-enzyme assays
