On the Stereochemistry of 2-Hydroxyethylphosphonate Dioxygenase
Stereochemical investigations have shown that the conversion of 2-hydroxyethylphosphonate to hydroxymethylphosphonate by the enzyme HEPD involves removal of the pro-S hydrogen at C2 and, surprisingly, the loss of stereochemical information at C1. As a result, the mechanisms previously proposed for HEPD must be re-evaluated.
متن کاملMechanistic inferences from stereochemistry.
I am still impressed that the textbook language of organic chemistry is so successful in explaining the reactions that we find in nature. Thismight not have been anticipated because we find that biological reactions are invariably stereospecific whereas nonbiological reactions are invariably not. This realization came to light about 150 years ago when Pasteur found that only half of chemically ...
متن کاملDictionary of Protein Stereochemistry
A computer-readable dictionary for protein structure refinement is presented. The dictionary is based on the set of interatomic bonds and bond angles previously derived from small-molecule structures by Engh & Huber [Acta Cryst. (1991), A47, 392-400]. The internal inconsistency of the set is discussed. Some preliminary results derived from several protein structures refined at atomic resolution...
متن کاملStereochemistry of Platinum Organometallics
The organometallic chemistry of platinum covers a huge field, as shown by a recent survey covering the crystallographic and structural data of almost one thousand organometallic derivatives. About nine percent of those derivatives exist as isomers and are summarized in this review and include distortion (90 %), cis trans (6%) and ligand isomerism (4%). These are discussed in terms of the coordi...
