A simple and efficient method to prepare isomorphous derivatives of protein crystals with xenon as a heavy atom is described. The method consists of exposing a crystal to xenon gas of pressures above 5 atm (~ 0.5 MPa) for several minutes and subseque

The optically active urobilin model compound 7 was synthesized, in which Me groups instead of H-atoms are bound to the asymmetric centers, thus preventing loss of chirality by tautomerization. The key intermediate of the eleven-step synthesis of 7 is

Cyanogenesis is a defense process of several thousand plant species. Hydroxynitrile lyase, a key enzyme of this process, cleaves a cyanohydrin into hydrocyanic acid and the corresponding aldehyde or ketone. The reverse reaction constitutes an importa

The X-ray crystal structure of native hydroxynitrile lyase from Hevea brasiliensis (Hb-HNL) has been determined at 1.1 A resolution. It refined to a final R of 11.5% for all data and an Rfree of 14.4%. The favorable data-to-parameter ratio at atomic

Most biological and many other molecules are chiral, i.e. they cannot be superimposed on their mirror image. The two mirror images of a chiral molecule are called enantiomers. Chiral molecules show the phenomenon of optical activity, i.e. a solution
