An amino acid sequence is described. The amino acid may comprise a signal sequence that is SEQ ID NO. 1a (or a variant or homologue or derivative or fragment thereof) that is expressed as a fusion protein that comprises a protein of interest. The signal sequence directs secretion of the protein of interest. The protein of interest may be a heterologous protein. Secretion of the fusion protein aids purification.
描述了一种
氨基酸序列。该
氨基酸可能包括一个信号序列,该信号序列是
SEQ ID NO. 1a(或其变异体或同源体或其片段),表达为包含所需蛋白质的融合蛋白质。信号序列指导所需蛋白质的分泌。所需蛋白质可以是异源蛋白质。融合蛋白质的分泌有助于纯化。
