[{"from": "human", "value": "Based on the given information, design a molecule that meets the desired specifications. The molecule is a non-proteinogenic L-alpha-amino acid that is L-propargylglycine which is carrying a hydroxy group at the 3R position. It has a role as an antimetabolite, an antibacterial agent, a bacterial metabolite and a fungal metabolite. It is a terminal acetylenic compound and a non-proteinogenic L-alpha-amino acid. It is functionally related to a L-propargylglycine. It is a tautomer of a L-beta-ethynylserine zwitterion."}, {"from": "gpt", "value": "[C][#C][C@H1][Branch1][#Branch2][C@@H1][Branch1][=Branch1][C][=Branch1][C][=O][O][N][O]"}]
