Introduction

Inverse protein folding aims to design amino acid sequences that form specific 3D structures, which is crucial for protein engineering and drug development. Traditional approaches often neglect vital biochemical characteristics that impact protein function. BC-Design introduces a new approach that combines structural data and biochemical attributes, using a dual-encoder architecture for enhanced accuracy. This framework, which surpasses current methods in sequence recovery and structural precision, demonstrates strong generalization and performs well with complex protein features.

Key Features of BC-Design:

  • Integrates structural and biochemical features for protein design.
  • Uses a dual-encoder system with a Structure Encoder for spatial relationships and a BC-Encoder for biochemical features.
  • A BC-Fusion module enables cross-modal feature interaction, enhancing alignment of structural and biochemical data.
  • Outperforms traditional methods with high sequence recovery (88.37%) and low perplexity (1.47) on the CATH 4.2 benchmark.
  • Exhibits robust generalization across diverse protein sizes, complexity levels, and structural classes.
