Experimental and theoretical studies of the effect of ferrum
triad metal cations on the activity of extracellular lectins of
Lentinus edodes
Abstract
The activity of extracellular lectins of the
basidiomycete Lentinus edodes (Berk.) Sing [Lentinula edodes
(Berk.) Pegler] has been shown to be related to the presence of definite
double-charged metal cations in the synthetic liquid medium of cultivation. The
effect of Fe2+, Co2+,
Ni2+ on the lectin activity has been
demonstrated to change with a symbate character in respect to the energies of
chelating reactions of metals hexaaqua complexes with the model ligand ethylene
glycol. At the initial steps of the lectins biosynthesis, the above metals
cations exert the greatest influence upon the lectin activityof L.
edodes.
