Task: Please give me a SMILES based on the description below.
Description: The molecule is an L-alpha-amino acid zwitterion obtained from L-2-amino-4-chloropent-4-enoic acid by transfer of a proton from the carboxy group to the amino group. It is the major species at pH 7.3. It is a tautomer of a L-2-amino-4-chloropent-4-enoic acid.
Result: C=C(Cl)C[C@H]([NH3+])C(=O)[O-]
