Mechanism of Inactivation of Enzyme Proteins by Ultraviolet Light

Abstract
In the report by A. D. McLaren and R. A. Luse on the "Mechanism of inactivation of enzyme proteins by ultraviolet light (2537 A)" [Science 134, 836 (22 September 1961)], two errors occur in the values given for Φ for enzymes in the last two lines of the table. The calculated value of Φ for ribonuclease is 0.03, not 0.30. The known value of Φ for trypsin is 0.015, not 0.105.
