    摘要: A simple and low-cost method of selectively modifying the C-terminal of a protein or peptide is provided. A method of modifying the C-terminal of a protein or peptide comprises forming an intramolecular oxazolone ring at the C-terminal of the protein or peptide that requires C-terminal modification, and then performing a ring-opening of the oxazolone ring to produce a protein or peptide with a modified C-terminal. Preferred forms include a method in which by reacting the oxazolone ring with a compound containing a nucleophilic group to effect an oxazolone ring-opening, a protein or peptide is produced in which the C-terminal is modified with the compound containing the nucleophilic group, as well as a method in which by reacting the oxazolone ring with an active esterifying agent to effect a ring-opening, the oxazolone is converted to an active ester, which by subsequent reaction with a compound containing a nucleophilic group, produces a protein or peptide in which the C-terminal has been modified with the compound containing the nucleophilic group.

    摘要: In a safety system for an elevator, slip detection means detects a slip between a drive sheave and a main rope. A safety gear is mounted to a car, the safety gear being electrically operated by an actuator to cause the car to make an emergency stop regardless of whether a running direction of the car is upward or downward. A safety gear controller cuts power supply to a hoisting machine motor and causes the safety gear to make a braking operation upon detection of the slip between the drive sheave and the main rope by the slip detection means.
