This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,519.

Summary of the Inventive Concept

This inventive concept applies the core technology of the original patent to develop novel systems, methods, and devices for environmental remediation, greenhouse gas reduction, wastewater treatment, and improved agricultural yield, leveraging targeted protein degradation to address pressing sustainability challenges.

Background and Problem Solved

The original patent focused on the targeted degradation of enhancer of zeste homolog 2 (EZH2) polypeptide for therapeutic applications. However, the core technology's potential extends beyond the pharmaceutical industry. This inventive concept addresses the need for innovative solutions to pressing environmental and sustainability challenges, such as pollution, climate change, and waste management, by repurposing the targeted protein degradation approach.

Detailed Description of the Inventive Concept

The new claims describe systems, methods, and devices that utilize bifunctional constructs to bind E3 ubiquitin ligase proteins and target pollutant proteins, leading to their degradation by the proteasome. These inventive concepts can be applied to various industries, including environmental remediation, agriculture, and waste management. For instance, the system for environmental remediation comprises a bifunctional construct that binds an E3 ubiquitin ligase protein and a target pollutant protein, promoting the degradation of the target pollutant protein and reducing environmental harm.

Novelty and Inventive Step

The new claims introduce a novel application of the core technology, shifting from therapeutic uses to environmental and sustainability-focused applications. The inventive step lies in recognizing the potential of targeted protein degradation to address complex sustainability challenges and developing systems, methods, and devices that achieve this goal.

Alternative Embodiments and Variations

Alternative embodiments may include variations in the bifunctional construct design, the choice of E3 ubiquitin ligase protein, or the target pollutant protein. Additionally, the inventive concept could be adapted for use in other industries, such as energy production or construction, where targeted protein degradation could provide innovative solutions for sustainability and environmental stewardship.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential, with applications in environmental remediation, agriculture, waste management, and other industries. The market demand for sustainable solutions is growing, and this technology could provide a competitive edge for companies seeking to reduce their environmental footprint and improve their sustainability credentials.
