The present invention relates to a complementation system comprising two fragments of photoactive yellow protein (PYP), or truncated fragments thereof, and its use with a fluorogenic hydroxybenzylidene rhodanine (HBR) analog for detecting interaction between biological molecules of interest, in particular between proteins of interest.
The present invention especially relates to a complementation system comprising a first PYP fragment comprising an amino acid sequence having at least about 70% identity with the amino acid sequence as set forth in SEQ ID NO: 23, or a truncated fragment thereof comprising at least 89 consecutive amino acids from the C-terminal end of said amino acid sequence; and a second PYP fragment comprising an amino acid sequence having at least about 70% identity with the amino acid sequence as set forth in SEQ ID NO: 34, or a truncated fragment thereof comprising at least 8 consecutive amino acids of said amino acid sequence.
本发明涉及一种由光活性黄蛋白(PYP)的两个片段或其截断片段组成的互补系统,及其与含氟羟基亚苄基罗丹宁(HBR)类似物一起用于检测相关生物分子之间的相互作用,特别是相关蛋白质之间的相互作用。
本发明尤其涉及一种互补系统,该系统包含第一个PYP片段,其氨基酸序列与SEQ ID NO:23 所述氨基酸序列至少具有约 70% 的同一性的氨基酸序列,或其截短片段,该片段包含所述氨基酸序列 C 端起至少 89 个连续氨基酸;以及第二PYP 片段,该片段包含与 SEQ ID NO: 34 所述氨基酸序列至少具有约 70% 的同一性的氨基酸序列,或其截短片段,该片段包含所述氨基酸序列的至少 8 个连续氨基酸。
