Crystal structure of the bifunctional enzyme phosphoribosyl isomerase A from Mycobacterium tuberculosis with bound light-controllable inhibitor. [PDF]
Acta Crystallogr F Struct Biol CommunWe have determined the crystal structure of an isomerase catalyzing two steps in histidine and tryptophan biosynthesis with a bound light‐switchable competitive inhibitor. The work explains the mode of action of the inhibitor and describes the discovery of a hitherto unknown third phosphate‐binding site of the enzyme.The enzyme phosphoribosyl isomerase

Ring closing reaction in diarylethene captured by femtosecond electron crystallography [PDF]
, 2013 The photoinduced ring closing reaction in diarylethene, which serves as a modelsystem for understanding reactive crossings through conical intersections, was directly observed with atomic resolution using femtosecond electron diffraction.

Predicting photoactivity in dithienylethene crystalline solids
IUCrJ, 2023 This commentary discusses the design of stimuli-responsive materials, specifically, light-responsive dithienylethene-based compounds. Recent progress in predicting photoactivity using a combination of theory and crystal structure landscape experiments is

Bistable Switching of π-Conjugation in a Dithienylethene-Bridged Luminescent Trityl Diradicaloid. [PDF]
Angew Chem Int Ed EnglPhotoswitches that affect π‐conjugation offer a powerful strategy for external manipulation of luminescent diradicals. Dithienylethene‐linked persistent trityl diradicaloids, DTE‐TTM2 and F6‐DTE‐TTM2, exhibit bistable switching of their optical, electrochemical and magnetic properties.

Quantitative Evaluation of Photoinduced Bending Speed of Diarylethene Crystals
Crystals, 2015 We investigated photoinduced crystal bending behavior of various photochromic diarylethenes. In all the diarylethene derivatives we used in this work, the relationship between the initial photoinduced bending speed and the crystal thickness was well ...
