Webreflects the activity of cystathionine β-synthase and cystathionine γ-lyase. For example, it is well known that L-cystathionine is observed in the urine of cystathionuric patients owing to a cystathionine γ-lyase deficiency.6) Thus, L-cystathionine is considered to be a key amino acid related to metabolic conditions. Thus, its quantitative WebDec 12, 2012 · Methods: An electrospray LC–MS/MS method preceded by a solid phase extraction step was developed for the measurement of CBS activity in cell extracts. Nonafluoropentanoic acid was used as an ionpair to provide the underivatized cystathionine the desired retention on a C18 column. Results pmol cystathionine/h/mg …
