Summary:The present invention relates to a flavin-based fluorescent protein variant having improved fluorescence intensity. The present invention also relates to a gene encoding a flavin-based fluorescent protein variant. The present invention relates to a technology that can overcome the limitations of conventional detection systems using fluorescent proteins, which have different fluorescence intensity depending on the presence and concentration of oxygen, and the limitations of fluorescent proteins using FMN cofactors, which are difficult to use due to low fluorescence signal. Thus, the present invention can be widely used in various biotechnology fields such as life science research, biosensors, biochips, disease diagnosis, and the like. 본 발명은 형광 세기가 향상된 플라빈 기반 형광 단백질 변이체에 관한 것이다. 또한, 본 발명은 플라빈 기반 형광 단백질 변이체를 코딩하는 유전자에 관한 것이다. 본 발명은 산소의 존재 유무 및 농도에 따라 형광세기가 차이가 발생하는 기존의 형광단백질을 이용한 검출 시스템의 한계와 낮은 형광 신호 때문에 사용이 어려운 FMN cofactor를 이용하는 형광단백질들의 한계를 극복할 수 있는 기술로 생명과학 연구, 바이오센서, 바이오칩, 질병진단 등 다양한 생명공학분야에 널리 이용될 수 있다.
