Structural Basis of the Light-Switchable Interaction between an Azobenzene Side Chain in a Biosynthetic Protein and α-Cyclodextrin.

Azobenzene derivatives, which show light-induced reversible trans↔cis isomerization, have gained increasing attention in the area of protein science. p-(Phenylazo)-L-phenylalanine (Pap) was recently employed to enable the light-controlled affinity pu…
