title: Folding and activation of recombinant human prorenin.
abstract: In vitro folding of mature renin, prorenin, and fused prorenin, all produced in denatured form in inclusion bodies in recombinant Escherichia coli, has been studied in order to evaluate the importance of prosequence in the folding of human renin. These studies have been compared with the in vivo folding and subsequent in vitro activation of recombinant human prorenin secreted by a nonbacterial expression system, namely Chinese hamster ovary (CHO) cells grown in serum-free medium. It is concluded that prosequence is essential in the folding of human renin and, therefore, the DNA coding for this sequence cannot be removed without affecting the recovery of active human renin from recombinant bacterial and nonbacterial systems.
