trinuclear การใช้

• Thermolysis of iron pentacarbonyl gives the trinuclear cluster, triiron dodecacarbonyl.
• Early work showed that it is trinuclear.
• The final step involves pyrophosphate held in the trinuclear Mg 2 + center acting as a catalytic base in an elimination reaction to form geranyl pyrophosphate.
• The trinuclear Mg 2 + complex is critical for binding DMAPP and stabilizing the pyrophosphate leaving group while the growing hydrocarbon tail wedges into a deep hydrophobic pocket.
• An FPPS-IPP-risendronate ternary complex demonstrated that risendronate binds to the trinuclear Mg 2 + complex and interacts with the hydrophobic pocket in a manner similar to DMAPP.
• A top view of the active site is shown in "'Inset 2 "'along with the aspartate mediated trinuclear Mg 2 + ( silver spheres ) catalytic center.
• Both the N-and C-terminal halves of the synthase contain aspartate-rich domains ( DDHFLE and DDYYP, respectively ) and the NSE amino acid motif ( NDLFSYQRE and NDVFSYQKE, respectively ), which bind trinuclear magnesium.
• "' D-orbital aromaticity "'is found in trinuclear tungsten W 3 O 9  " and molybdenum Mo 3 O 9  " metal clusters generated by laser vaporization of the pure metals in the presence of oxygen in a helium stream.
