Glucosinolate sulfatase (GSS) activity in Psylliodes chrysocephala adults. (a) Crude tissue homogenates were prepared from dissected guts and the remaining body tissues, and gut tissue homogenates were fractionated into membrane fraction and soluble protein fraction by centrifugation. Samples were incubated with a mixture of eight different glucosinolates (GLS) for 2 h at 35 °C, and desulfo-glucosinolates were quantified by LC-MS/MS using external standard curves. (b) Comparison of GSS activity in crude gut homogenates towards eight different glucosinolates. Means + SD of n = 4 biological replicates. n.d., not detected; 2OH3But, 2-hydroxy-3-butenyl; 3But, 3-butenyl; 4MSOB, 4-methylsulfinylbutyl; 4MTB, 4-methylthiobutyl; I3M, indol-3-ylmethyl; 2PE, 2-phenylethyl.
