COMMENTARY
LITERATURE
ENZYME 3D STRUCTURE
a high concentration of lactate has a weak inhibitory effect on the pyruvate reduction reaction activity but is meaningful for a significant lactate oxidation rate as the K m value of LDHA for L-lactate is very high
-
slight inhibition at 5 mM
-
less than 10% inhibition
-
3.73 mM, 50% inhibition of recombinant enzyme
-
1 mM, 29% inhibition
-
lactate indirectly inhibits hexokinase activity, which results from its cellular redistribution, attributed to alterations of hexokinase structure. No modulation of hexokinase activity in heart or kidney
-
induces dissociation of enzyme dimer and unfolding of the enzyme at 0.8 mM, but no aggregation at 25°C or 40°C even at high protein concentrations, inactivation kinetics
-
complete inhibition at 10 mM, 58.3% inhibition at 1 mM
-
noncompetitive
-
about 70% inhibition at 10 mM
-
stronger inhibitory effect on strain ATCC 367 than on IOEB 9809
-
at 50 mM and above
