# 10.3 Interface Design Principles

> Interface Design Principles (Module 10: The Assembler). Key concept: Stable interfaces need BSA, shape complementarity, H-bonds. Engineer an interface with enough buried surface area to hold a complex together.

Interface Design Principles (Module 10: The Assembler). Key concept: Stable interfaces need BSA, shape complementarity, H-bonds. Engineer an interface with enough buried surface area to hold a complex together.

- Engineer an interface with enough buried surface area to hold a complex together
- Balance hydrophobic contact, hydrogen bonding, shape complementarity and clashes
- State the buried surface area convention you are using: roughly 600 Å² per chain is a floor, and a designed homodimer usually wants 800–1000
