摘要: An unnatural amino acid may have a structure as shown in formula (1) or may be an enantiomer thereof:
Such unnatural amino acid may be used, e.g., in recombinant proteins. A recombinant protein may contain such unnatural amino acid and a protein conjugate prepared from the recombinant protein. The unnatural amino acid can be simple and convenient to prepare, safe in nature, difficult to inactivate when inserted into a protein, and may have a high binding rate with a coupling moiety, and the obtained conjugate is higher in stability. The unnatural amino acid is applicable to numerous fields, especially in preparation of a recombinant protein or a recombinant protein conjugate.
