Proteins (or protein complexes) that assist in folding post-translationally, by creating a favorable folding environment surrounding the protein, are called [ans2].  Proteins (or protein complexes) that prevent folding during translation (co-translationally), thereby allowing all parts of the protein to be present for proper folding, are called [ans1].
