(A, D, F) Dansylated (DNS) cis-substrates were incubated either without (lane a) or with (lane b) XeHypBA1, XeHypBA2, or XeHypAA and the reaction products were analyzed by TLC. Ara-Hyp-DNS (lane 1), Ara2-Hyp-DNS (lane 2), Ara3-Hyp-DNS (lane 3), and Ara4-Hyp-DNS (lane 4) were used as substrates. (B) TLC analysis of XeHypBA1 reaction products. l -arabinose standard (lane 1). Ara-Hyp (lane 2) and Ara2-Hyp (lane 3) were incubated either without (lane a) or with (lane b) XeHypBA1. (C, E) HPAEC-PAD analysis of XeHypBA1or XeHypBA2 reaction products. β-Ara2 standard (a, d); l-arabinose standard (b); Ara3-Hyp standard (e); β-Ara2 incubated with XeHypBA1 (c); Ara3-Hyp incubated with XeHypBA2 (e).
