Abstract excerpt

Bioluminescence spectra of the wild-type recombinant Luciola mingrelica firefly luciferase and its mutant form with the His433Tyr point mutation were obtained within the pH 5.6-10.2 interval. The spectra are shown to be a superposition of the spectra of the three forms of the electronically excited reaction product oxyluciferin: ketone (lambdamax = 618 nm), enol (lambdamax = 587 nm), and enolate-ion (lambdamax =...
