abstract：:The role of S. cerevisiae YDJ1 protein (YDJ1p) in polypeptide translocation across membranes has been examined. A conditional ydj1 mutant strain (ydj1-151TS) is defective for import of several polypeptides into mitochondria and alpha factor into the endoplasmic reticulum at 37 degrees C. These defects are suppressed b...
