An isolated polynucleotide encoding a modified luciferase polypeptide and novel coelenterazine- based substrates. The OgLuc variant polypeptide has at least 60% amino acid sequence identity to SEQ ID NO: 1 and at least one amino acid substitution at a position corresponding to an amino acid in SEQ ID NO: 1. The OgLuc variant polypeptide has at least one of enhanced luminescence, enhanced signal stability, and enhanced protein stability relative to the corresponding polypeptide of the wild-type Oplophorus luciferase.
一个编码修改后的荧光酶多肽和新型荧光素基底的孤立的多聚核苷酸。OgLuc变体多肽至少具有与SEQ ID NO: 1的氨基酸序列相同性的60%,并且至少在一个位置上具有与SEQ ID NO: 1中的氨基酸对应的氨基酸替换。相对于野生型Oplophorus荧光酶的相应多肽,OgLuc变体多肽至少具有增强的荧光、增强的信号稳定性和增强的蛋白稳定性中的至少一种。
