Fig. 2From: Isolation and functional verification of an aspartate aminotransferase gene from Neoporphyra haitanensisMultiple sequence alignment of NhAATs with AATs from N. yezoensis and C. crispus. The binding sites of the PLP are marked with blue asterisks, and the binding sites of the polypeptide are marked with red asterisks. The amino acid residue in black boxes is the catalytic residueBack to article page
