To test how far into the protein-conducting channel of the translocon complex a nascent polypeptide domain must move before it can fold, we analyzed the folding of in vitro translated products of truncated mRNAs encoding the Semliki Forest virus capsid protease domain (Cp) during translocation into microsomes. Cp folded when the C-terminal linker connecting it to the peptidyltransferase center was 64 amino acids or longer. This means that to fold, Cp must exit the translocon channel. With an uncleaved signal sequence, about one out of four of the Cp domains could undergo folding with a C-terminal linker of only 38-66 amino acids. This suggested that the constraint imposed on folding by the translocon complex may be less stringent for signal-anchored membrane proteins.
