    The folding of the bacterial protease subtilisin BPN' (SBT) is dependent on its 77-residue prosegment, which is then autocatalytically removed to give the mature enzyme. Mature subtilisin represents a class of proteins that lacks an efficient folding pathway. Refolding of mature SBT is extremely slow unless catalyzed by the independently expressed prosegment, leading to a bimolecular complex.
