Hydroxylamine reactivity of the C. nuchalis wild type SWS1 pigment. Absorption spectra recorded t = 0 min after hydroxylamine addition (black line), and t = 120 min (grey line), followed by light bleaching (broken line). Right: The absorbance values at 403 nm (broken line) and 363 nm (black line) were plotted as a function of time after addition of hydroxylamine. Half-life for the formation of the retinal oxime in the presence of hydroxylamine was obtained by fitting the plot to a single exponential function.
