Heterologous Protein Secretion from Yeast
Abstract
Secretion of calf prochymosin from yeast yields fully activable zymogen while production in the yeast cytoplasm yields insoluble, unactivable enzyme with aberrant disulfide bonding. Factors that increase the efficiency of secretion of prochymosin from yeast are use of a yeast secretion signal sequence, integration of the transcriptional unit into the yeast genome, and specific mutations in a number of host cell genes. In combination, these factors increase the secretion of calf prochymosin from less than 1 percent to more than 80 percent of the amount produced. Host mutations that increase prochymosin secretion also increase bovine growth hormone secretion more than 15-fold. These discoveries may be generally useful for production of many secreted mammalian proteins made inside microorganisms as insoluble aggregates.

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.
