Pro-sequence of subtilisin can guide the refolding of denatured subtilisin in an intermolecular process.

Abstract

Subtilisin E, an alkaline serine protease consisting of a single polypeptide chain of 275 amino acids is produced from a pre-pro-protein. The pre-sequence functions as the signal peptide for protein secretion across the membrane. Deletion of the pro-sequence yields mature but inactive subtilisin: the 77-amino acid pro-sequence must precede the mature subtilisin to guide the latter into an active conformation. Pro-subtilisin denatured in 6 M guanidine-HCl can be self-processed to the active enzyme intramolecularly, with concomitant cleavage of the pro-sequence, when dialysed against renaturing buffer. We have constructed an active-centre mutant of pro-subtilisin (Asp 32----Asn) which is not processed to active enzyme, unlike the wild-type pro-subtilisin, because intramolecular processing is prevented. Here we report an intermolecular pathway for the refolding of the inactive mature protein to an active enzyme in vitro with the aid of exogenously added pro-sequence. We establish conditions under which the mature inactive form, as well as acid-denatured subtilisins Carlsberg and BPN', can be renatured by the mutant pro-subtilisin.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
