Figure 4From: Secreted fungal sulfhydryl oxidases: sequence analysis and characterisation of a representative flavin-dependent enzyme from Aspergillus oryzaeAbsorption spectrum of purified AoSOX1. Three peaks are visible: at 275 nm, 370 nm and at 440 nm with a shoulder at 465 nm. The inset shows the peaks in visible region before (continuous line) and after denaturation (dotted line); in the latter case the peaks are due to the released FAD cofactor.Back to article page
