✦ Synopsis


The cover picture shows a photoswitchable affinity label (PAL) in its trans form bound noncovalently to bovine carbonic anhydrase 2. Potential reactive nucleophiles surrounding the PAL are highlighted in yellow. Histidines 2 and 3, which eventually undergo the bioconjugation, are shown in red. After bioconjugation, the affinity label can be withdrawn from the active site through photoisomerization (upper left corner). For details see the article by J. H. Harvey and D. Trauner on p. 191 ff.
