Student Use Cases

Structural biology for USMLE Step 1 · FMGE · PLAB — powered by the Surface 2 model ensemble

7 Use CasesUSMLE High-YieldNo GPU required
What happens
  1. EntityGraph identifies ibuprofen (DRUG) + COX-2 / PTGS2 (PROTEIN) from the question.
  2. Alpha is called on the PTGS2 UniProt sequence — returns a rapid structure (<2 s).
  3. Mol* viewer renders the binding pocket inline with Arg120, Tyr355, Ser530 annotated.
Student value

Turns a memorisable pharmacology fact into a spatially understood mechanism — you see why selectivity exists.

Exam relevance

USMLE Step 1 · Pharmacology

What happens
  1. Alpha predicts wild-type HBB structure.
  2. Beta models the p.Glu6Val mutant variant.
  3. Side-by-side Mol* shows the hydrophobic patch driving fibre polymerisation.
Student value

HbS polymerisation becomes visually obvious — valine substituting glutamate creates a sticky surface.

Exam relevance

USMLE Step 1 · Biochemistry

What happens
  1. Beta models the resistant PBP2a + beta-lactam substrate complex.
  2. Split viewer compares altered binding pocket vs wild-type PBP.
  3. EntityGraph links MRSA → PBP2a → resistance → daptomycin / linezolid alternatives.
Student value

The highest-yield AMR teaching point — shown visually for the first time.

Exam relevance

USMLE Step 1 · Microbiology · AMR

What happens
  1. Gamma models spike-ACE2 interaction with the p.Asn501Tyr variant.
  2. Epitope residues are highlighted in Mol*.
  3. Prefusion vs postfusion conformations explained — why prefusion drives stronger neutralising antibodies.
Student value

Foundation for understanding all modern subunit vaccines and immune evasion.

Exam relevance

USMLE Step 1 · Immunology

What happens
  1. Alpha + Beta model intrinsically disordered Amyloid-beta conformations.
  2. Fibril polymorphs are visualised across timepoints.
  3. EntityGraph links mechanism to BACE1 inhibitor therapeutic targets.
Student value

Explains why current Alzheimer's treatments have failed — clinical reasoning depth.

Exam relevance

USMLE Step 1 · Pathology · Neurology

What happens
  1. Alpha models the channel pore + voltage-sensing helices.
  2. Mutation site highlighted in Mol*.
  3. EntityGraph links KCNQ1 → Long QT Type 1 → torsades de pointes → management.
Student value

Prevents treating channelopathies as isolated facts — teaches mechanistic disease reasoning.
