The same protein can deform into multiple different 3D shapes, called conformations. Some proteins are rigid and exist almost exclusively in a single conformation. It is probably easier to determine the 3D structure of proteins with a single, dominant conformation. Other proteins don't have well defined conformations, and are more like a tangle of rope that can bend in many different ways
