D-Amino acids are increasingly being recognized as important signaling molecules in mammals, including humans. D-Serine and D-aspartate are believed to act as signaling molecules in the central nervous system. Interestingly, several other D-amino acids also occur in human plasma, but

The increase in our understanding of D-amino acid function and distribution in mammals is in many ways a result of the initial development of sensitive enantioselective separation strategies that allow for quantification in real biological samples. This article reviews progress

Asparaginase from the hyperthermophilic microorganism Archaeoglobus fulgidus was cloned and expressed in Escherichia coli as a fusion protein with a polyhistidine tail. After heat treatment to denature most of the native E. coli proteins, the enzyme was purified by an

A sensitive chiral capillary HPLC-MS/MS method well suited for the determination of amino acid enantiomers in biological samples was developed. The method involved precolumn derivatization of the sample with 7-fluoro-4-nitrobenzoxadiazole (NBD-F). After derivatization, NBD-amino acids were stacked on a C18
