Task: Please create a description for a molecule based on its representation.
SMILES: [NH3+][C@@H](CS)C(=O)NCC(=O)[O-]
Constraint: Answer the question with full sentences.
Result: The molecule is the zwitterion of L-cysteinylglycine resulting from the transfer of a proton from the hydroxy group of glycine to the amino group of cysteine. Major microspecies at pH 7.3. It has a role as an Escherichia coli metabolite, a Saccharomyces cerevisiae metabolite and a human metabolite. It is a tautomer of a L-cysteinylglycine.
