  1. Activity (µmol min−1 mgprotein−1) was calculated from linear regression, with associated standard errors, of the rate of oligosaccharide consumption from two independent reactions measured every 2 min over a 10 min period measured by HPAEC-PAD. Reduced oligosaccharides were generated by NaBH4 reduction as described in the methods. Reported values means and standard deviations from duplicate assays (n = 2).
