HPAEC-PAD product spectra of Y421 (A) and Y439 (B) variants. Products were obtained from reactions containing 0.5 M sucrose and 2 U/mL of enzymatic activity in 50 mM Soerensen buffer pH 6.6. Samples were evaluated at sucrose conversion of around 70%. (1) 1-kestose, (2) blastose, (3) disaccharide, (4) 6-kestose, (5) disaccharide, (6) neokestose, (7) tetrasaccharide Glu-(Fru)3, (8) disaccharide, (9) tetrasaccharide, (10) 6-nystose, (11) tetrasaccharide, (12) pentasaccharide and (13) hexasaccharide. Signal intensities may vary between measurements, thus, wild-type Bm-LS was measured with every sample batch to allow comparison, except for samples in Figure 5B.
