Figure 6From: Secreted fungal sulfhydryl oxidases: sequence analysis and characterisation of a representative flavin-dependent enzyme from Aspergillus oryzaeEquilibrium denaturation curves of AoSOX1. Intrinsic tryptophan fluorescence (triangle), flavin fluorescence (filled square) and residual activity (empty circle) of AoSOX1 were monitored at increasing guanidinium hydrochloride (GndHCl) concentration.Back to article page
