I. Hamachi et al., PHOTOSWITCHING OF THE ENZYMATIC-ACTIVITY OF SEMISYNTHETIC RIBONUCLEASE S' BEARING PHENYLAZOPHENYLALANINE AT A SPECIFIC SITE, Chemistry Letters, (6), 1998, pp. 537-538
Photoswitching of the enzymatic activity of ribonuclease S' was succes
sfully carried out by site specific incorporation of phenylazophenylal
anine into S-peptide skeleton by semisynthesis.
