title: Glutamyl-taurine is the predominant synaptic taurine peptide.
abstract: Several taurine-containing peptides have been identified from trichloracetic acid extracts of synaptosomes and their subcellular vesicles prepared from calf brain. These peptides contain aspartic and glutamic acids, serine and taurine, and are often present in an N-acetylated form. The peptides were isolated as single spots by TLC. Glutamyl-taurine was found to be the predominant structure when analyzed by fast atom bombardment (FAB) mass spectrometry.
