We investigated how a genetically engineered
resilin fusion protein modifies cellulose surfaces. We characterized
the pH-responsive behavior of a resilin-like polypeptide
(RLP) having terminal cellulose binding modules (CBM) and
showed its binding to cellulose nanofibrils (CNF). Characterization
of the resilin fusion protein at different pHs revealed
substantial conformational changes of the protein, which were
observed as swelling and contraction of the protein layer bound
to the nanocellulose surface. In addition, we showed that
employment of the modified resilin in cellulose hydrogel and
nanopaper increased their modulus of stiffness through a cross-linking effect.
