COMMENTARY 
LITERATURE
IMAGE
AgCl
-
immobilized enzyme: 38% inhibition at 0.1 mM, 67% inhibition at 1 mM, complete inhibition at 10 mM. Free enzyme: 49% inhibition at 0.1 mM, 71% inhibition at 1 mM, 95% inhibition at 10 mM
CuSO4
-
immobilized enzyme: 25% inhibition at 0.1 mM, 37% inhibition at 1 mM, 65% inhibition at 10 mM. Free enzyme: 30% inhibition at 0.1 mM, 42% inhibition at 1 mM, 79% inhibition at 10 mM
Fe3+
-
20 ng/ml medium, 30% inhibition of the free enzyme, 22% inhibition of the immobilized enzyme
FeCl3
-
immobilized enzyme: 8% inhibition at 0.1 mM, 21% inhibition at 1 mM, 35% inhibition at 10 mM. Free enzyme: 13% inhibition at 0.1 mM, 29% inhibition at 1 mM, 40% inhibition at 10 mM
HgCl2
-
immobilized enzyme: 54% inhibition at 0.1 mM, 61% inhibition at 1 mM, 79% inhibition at 10 mM. Free enzyme: 61% inhibition at 0.1 mM, 75% inhibition at 1 mM, 91% inhibition at 10 mM
MgSO4
-
11% inhibition of the immobilized enzyme at 10 mM, 21% inhibition of the free enzyme at 10 mM
Cu2+
-
20 ng/ml medium, 42% inhibition of the free enzyme, 80% inhibition of the immobilized enzyme
D-glucose
-
D-glucose acts as an inhibitor of the transfructosylation reaction, the decrease of glucose concentration by yeast in the medium by 16-19% results in the increased degree of levan polymerisation (by 6 to 9%) and efficiency of levan synthesis (by 9 to 11%)
D-glucose
-
shows high product inhibition in lactosucrose formation, D-glucose is therefor eliminated from the reaction system of lactosucrose production by glucose oxidase
EDTA
the presence of 0.05 mM EDTA results in a decrease in the enzymatic activity by about 80%
Hg2+
-
20 ng/ml medium, 67.5% inhibition of the free enzyme, 54.3% inhibition of the immobilized enzyme
high ionic strength
-
suppresses transfer of fructosyl residues, especially in synthesis of high molecular weight levan, suppresses hydrolysis of levan, effect occurs with almost the same degree in hydrolysis of both low and high molecular weight levans
-
high ionic strength
-
under conditions of high ionic strength, only levan with an average degree of polymerization of 120 is synthesized with a reasonable yield
-
Mn2+
-
20 ng/ml medium, 80% inhibition of the free enzyme, 75% inhibition of the immobilized enzyme
NaCl
-
immobilized enzyme: 20% inhibition at 0.1 mM, 29% inhibition at 1 mM, 50% inhibition at 10 mM. Free enzyme: 26% inhibition at 0.1 mM, 40% inhibition at 1 mM, 55% inhibition at 10 mM
NaCl
-
30% of the protein is precipitated at 2 M NaCl
proteinase K
-
90% remaining activity after incubation at 37°C for 1 h
-
SDS
-
immobilized enzyme: 11% inhibition at 0.1 mM, 21% inhibition at 1 mM, 48% inhibition at 10 mM. Free enzyme: 14% inhibition at 0.1 mM, 27% inhibition at 1 mM, 52% inhibition at 10 mM
sucrose
-
above 300 mM, inhibition of transferase activity, not hydrolase activity
Zn2+
-
20 ng/ml medium, 75% inhibition of the free enzyme, 70% inhibition of the immobilized enzyme
