Elfin

Elfin constructs complex protein architectures from compatible smaller protein building blocks to design large-scale (nanometer–micron) protein assemblies guided by target shapes.

Key Features:

• Interactive design environment: Enables exploration of combinations of compatible building blocks to assemble single-chain and multiple-chain protein structures.
• CAD-directed automated design: Allows users to define target shapes that guide automated assembly and geometry of protein architectures.
• Sequence-agnostic shape construction: Supports rapid construction of protein shapes without requiring specification of amino acid sequences.
• Multiscale architecture support: Targets large-scale protein structures spanning nanometer to micron length scales.

Scientific Applications:

• Protein Engineering: Facilitates design of novel macromolecules with specific functions or properties relevant to therapeutic and industrial biotechnology applications.
• Material Science: Enables creation of protein-based materials with custom shapes and tailored mechanical, chemical, or biological characteristics.
• Structural Biology: Provides a platform to explore structural aspects of proteins and their interactions at macro scales.

Methodology:

Implemented as a Blender add-on that leverages compatible protein building blocks, permitting interactive assembly or automated, CAD-guided assembly into predefined target shapes and supporting single-chain and multiple-chain architectures.
