By the method of IR spectroscopy it is established that the process
of sorption of celiase, trypsin, chymotrypsin, streptase, plasminogen,
and plasmin by monocarboxylcellulose (the content of COOH groups is 15
wt.%) is mainly identical. The determining role in the mechanism of binding
of monocarboxylcellulose with the considered medicinal enzymes belongs
to electrostatic interactions with the formation of ionic bonds between
the COO– groups of the matrix and charged amine groups of protein
molecules. It is established that the process of interaction of plasmin
with oxidized cellulose takes a more active course than with other investigated
enzymes. It is shown that the activity of interaction of the enzymes with
monocarboxylcellulose can be evaluated by a change in the relative intensity
of the band of stretching vibrations of C=O groups.
