Techniques for Measuring the Activity of Carboxylic Acid:CoA Ligase and Acyl‐CoA:Amino Acid N‐Acyltransferase: The Amino Acid Conjugation Pathway

of xenobiotic carboxylic acids are metabolized to their amino acid conjugates via a pathway that exists primarily in liver and kidney. This conjugation occurs in a two?step pathway catalyzed by two distince types of enzymes, ligases and transferases

Amino acid composition

) to check derivatisation and chromatography efficiency and to allow quantitation of samples. Note that the Fmoc-amino acid derivatives are stable for 24 h, allowing many samples to be prepared in advance and loaded onto an autosampler for injection

3 H‐labeled radioligand (NEN Life Sciences): e.g., [3 H]D‐(−)‐3‐(2‐carboxy‐piperazine‐ 4‐yl)propyl‐1‐phosphonic acid ([3 H]CPP); [3 H]‐(±)‐cis ‐4‐phosphono‐methyl‐2‐piperidine carboxylic acid ([3 H]CGS 19755); or [3 H](±)‐E ‐2‐amino
