Abstract
A lysosomal thiol protease cathepsin H has been synthesized in vitro and shown to undergo co-translational segregation into the lumen of microsomal vesicles. Using cell-free synthesis, a 36 K Da cathepsin H was found to be synthesized exclusively on membrane-bound polysomes. When the microsomal membranes were present during translation, a glycosylated 41 K Da proenzyme appeared in the microsomal lumen. This proenzyme was converted to a 34 K Da protein by endoglycosidase H treatment. These results suggest that the nascent chain of cathepsin H has a transient N-terminal prepropeptide.
