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.
一个编码改良荧光酶多肽和新型荧光素基底底物的孤立的多聚核苷酸。OgLuc变体多肽至少具有与SEQ ID NO: 1的氨基酸序列相似性达到60%,并且至少在一个位置上具有至少一种氨基酸替换,该位置对应于SEQ ID NO: 1中的氨基酸。OgLuc变体多肽至少具有增强的发光性、增强的信号稳定性和增强的蛋白稳定性中的至少一种,相对于野生型Oplophorusluciferase的相应多肽。
