In the context of these functional rearrangements, these tertiary or quaternary structures are usually referred to as " conformations ," and transitions ...

Bioinformatics

... the protein can only function correctly if it is folded in a very special and individual way (if it has the correct secondary , tertiary and quaternary structure). The prediction of this folding just by looking at the amino acid sequence is quite difficult. Several methods for computer predictions ...
