The intersystem crossing rate is enhanced in LOV2 compared with flavin mononucleotide in solution, likely due to a heavy-atom effect of the nearby conserved cysteine C450.
Quoted textsource-backed
The ISC rate is enhanced in LOV2 as compared to flavin mononucleotide (FMN) in solution, which likely results from a heavy-atom effect of a nearby conserved cysteine, C450.
The proximity of the conserved cysteine to FMN enables formation of a covalent adduct between FMN and cysteine and facilitates rapid electronic formation of the reactive FMN triplet state.
Quoted textsource-backed
The proximity of the cysteine to FMN thus not only enables formation of a covalent adduct between FMN and cysteine, but also facilitates the rapid electronic formation of the reactive FMN triplet state.
Enhancement of the intersystem crossing rate in LOV2 is induced through weak electron donation by the conserved cysteine, which mixes FMN pi-electrons with heavy sulfur orbitals and manifests as quinoid character in the ground electronic state of oxidized FMN.

Thus, enhancement of the ISC rate in LOV2 is induced through weak electron donation by the cysteine which mixes the FMN pi-electrons with the heavy sulfur orbitals, manifesting itself in a quinoid character of the ground electronic state of oxidized FMN.
In LOV2, the primary photophysical event involves intersystem crossing from the singlet-excited state to the triplet state.

In LOV2, the blue-light sensitive domain of phototropin, the primary photophysical event involves intersystem crossing (ISC) from the singlet-excited state to the triplet state.
