[Campbell Biology P.132] What are 'intrinsically disordered proteins' as described in the text? | Practice Question

What are 'intrinsically disordered proteins' as described in the text?

  • A: Proteins that have a stable, well-defined 3-D structure at all times.
  • B: Proteins that do not have a distinct 3-D structure until they interact with a target protein or other molecule.
  • C: Proteins that primarily form strong covalent bonds with water molecules.
  • D: Proteins that are exclusively found in prokaryotic cells and are involved in cell wall synthesis.

Explanation

The text defines 'intrinsically disordered proteins' by stating: 'A growing body of biochemical research has revealed that a significant number of proteins, or regions of proteins, do not have a distinct 3-D structure until they interact with a target protein or other molecule.'
