Structural Bioinformatics interview questions

Molecular structures, prediction limits and structure-based analyses.

6 questions, each with a worked answer

How would you assess confidence in a predicted protein structure? Intermediate Scenario
Why might a good docking score fail to predict experimental binding? Fundamentals Concept
How do pLDDT and PAE answer different structure-confidence questions? Intermediate Concept
How would you validate a proposed ligand-binding pocket? Intermediate Scenario
How can receptor flexibility invalidate a docking conclusion? Advanced Concept
Why can structural similarity coexist with different protein functions? Advanced Concept

About Structural Bioinformatics

Structural bioinformatics analyses and predicts the three-dimensional shapes of proteins and other molecules. It uses experimental structures, from X-ray crystallography, cryo-EM and NMR, together with prediction tools such as AlphaFold. Structures support docking, binding-site analysis, design and explaining the effect of mutations.

Knowing the confidence and limits of a model matters as much as producing one.

Fundamentals: 1
Intermediate: 3
Advanced: 2

What these questions test

Assess structure model uncertainty: Identify structure regions and molecular claims that need experimental validation.
