title: Structure of a Gla-containing dipeptide. The crystal structure of (+/-)-N-carbobenzoxy-(gamma,gamma'-DI-tertbutyl)-gamma-carboxyglutamylglycine ethyl ester.
abstract: The crystal and molecular structure of a dipeptide containing a blocked gamma-carboxyglutamyl (Gla) residue is presented. Two intermolecular hydrogen bonds link the amides with carbonyl groups in the dipeptide backbone, but the protected gamma-carboxy groups on the modified glutamic acid are not hydrogen bonded.
