Tryptic digestion of immobilized D‐amino acid oxidase
FEBS Letters, 1978 Received 20 December 1977 1. Introduction The activity of an enzyme is dependent on its conformation and on the structure of its active site. Chemical modification and specific labelling of an active site are useful techniques for the analysis on its structure; however, they often result in undesirable changes in enzyme conformation.
