This is
supported by the results of Faulds et al. (2003), who investigated
the specificity of FAEs for feruloylated WEAX and WUAX and found
for all three FAEs (representatives of the FAE types A, B and C) a
preference for WEAX. As reUmChlE possessed a type B FAE side
activity (like the native enzyme; (Nieter et al., 2015)), a comparable
mode of action is suggested. Additionally, reUmChlE treated
doughs were less sticky and showed a good workability compared
to the reference sample. The improved dough handling properties
can be explained by the reUmChlE-mediated depolymerisation of
the cross-linked AX network. Partial removal of the ferulic acid
linkages should result in lower molecular mass pentosans which
possess a higher water holding capacity.
