Enzyme activity of truncated Fda1 mutants by C-PAGE. Enzyme activity of (c) Fda1Δ145 and (d) Fda1Δ395 on fucoidans from F. vesiculosus (F.ve), F. evanescens (F.ev), T. ornata (T.o), S. cichorioides (S.c) and U. pinnatifida (U.p), and standard (st). Both enzymes show activity on all the tested substrates to a comparable degree. The lowest band (**) of the standard (St), resulting from FFA2 treatment of fucoidan from F. evanescens, corresponds to a tetra-saccharide of (1→4)- and (1→3)-linked α-l-fucosyls with each fucosyl residue sulphated at C2; total mass has been calculated to be 972 Da [27].
