Scientists have discovered a new enzyme, which gives decisive insights into protein import in specific cellular organelles (peroxisomes). Researchers report that the enzyme Ubp15p collaborates with two other proteins to convert the protein transport machinery back into its initial condition after work has been completed. The enzyme detaches a specific signal sequence from a protein which is important for transportation and recycling of this protein.
