چکیده
Mycenon (C11H5Cl3O3), a new inhibitor of isocitrate lyase (EC 4.1.3.1) was isolated from the culture broth of a basidiomycete, Mycena sp. Mycenon is a novel chlorinated benzoquinone derivative which is also active against bacteria and fungi. Malate synthase (EC 4.1.3.2) the second key enzyme of the glyoxylate cycle was not affected by mycenon. Isocitrate lyase preparations from plants, bacteria and fungi were sensitive. The following Ki-values for mycenon have been determined: Ricinus communis, 5.2 microM; Acinetobacter calcoaceticus, 11 microM; Neurospora crassa, 7.4 microM. The structure of mycenon has been determined by a single crystal X-ray analysis.

Multisite inhibition of Pinus pinea isocitrate lyase by phosphate.
Our results show that the phosphate ion is a nonlinear competitive inhibitor of Pinus pinea isocitrate lyase. In addition, this compound induces a sigmoidal response of the enzyme, which usually exhibits standard Michaelis-Menten kinetics. This peculiar behavior of P. pinea isocitrate lyase could be explained by a dimer (two-site) model, in which phosphate binds cooperatively, but the affinity ...
متن کاملPurification and regulatory properties of isocitrate lyase from Escherichia coli ML308.
Isocitrate lyase was purified to homogeneity from Escherichia coli ML308. Its subunit Mr and native Mr were 44,670 +/- 460 and 17,000-180,000 respectively. The kinetic mechanism of the enzyme was investigated by using product and dead-end inhibitors of the cleavage and condensation reactions. The data indicated a random-order equilibrium mechanism, with formation of a ternary enzyme-isocitrate-...
متن کاملDegradation of pentachlorophenol by Mycena avenacea TA 8480--identification of initial dechlorinated metabolites.
Cultures of the basidiomycete Mycena avenacea TA 8480 were shown to metabolize pentachlorophenol (PCP), 2,3,5,6-tetrachloro-p-hydroquinone (TeCHQ), and 2,3,5,6-tetrachloro-p-benzoquinone (TeCBQ). The first metabolite of the PCP degradation pathway was identified as TeCBQ which in a second reaction is reduced to the hydroquinone TeCHQ. Subsequently dechlorination of TeCHQ yielded 3,5,6-trichloro...
متن کاملCrystal structures of 2-methylisocitrate lyase in complex with product and with isocitrate inhibitor provide insight into lyase substrate specificity, catalysis and evolution.
Two crystal structures of the C123S mutant of 2-methylisocitrate lyase have been determined, one with the bound reaction products, Mg(2+)-pyruvate and succinate, and the second with a bound Mg(2+)-(2R,3S)-isocitrate inhibitor. Comparison with the structure of the wild-type enzyme in the unbound state reveals that the enzyme undergoes a conformational transition that sequesters the ligand from s...
