Structural Basis for Substrate Channelling of a Fatty Acid - oxidation Multienzyme Complex

چکیده
C66 We have measured the spin-polarized electron momentum density distributions (magnetic Compton profiles) of UGe2 using the synchrotron-based magnetic Compton scattering technique. The spin moment of UGe2 has been determined as -1.15 μB at 10 K with an applied magnetic field of 0.5 T. Compared with the saturated magnetization of +1.40 μB, we have determined the orbital moment at +2.55 μB. The magnetic Compton profiles are decomposed into partial profiles by fitting with the U-5f atomic profiles with different magnetic quantum number m. From the fitted results, we estimated the orbital moment at +2.90 μB. It gives a slightly higher value since this estimation does not take account of the partial quenching of the orbital moment due to hybridization. We also found that the shape of the magnetic Compton profiles depend on temperature, indicating the spin-polarized, ground-state wave-functions vary with temperature.

Structural basis for channelling mechanism of a fatty acid beta-oxidation multienzyme complex.
The atomic view of the active site coupling termed channelling is a major subject in molecular biology. We have determined two distinct crystal structures of the bacterial multienzyme complex that catalyzes the last three sequential reactions in the fatty acid beta-oxidation cycle. The alpha2beta2 heterotetrameric structure shows the uneven ring architecture, where all the catalytic centers of ...
متن کاملRegulation of Fatty Acid Oxidation Kinetic implications of metabolite channelling in /?-oxidation
Introduction Direct transfer of metabolites between consecutive enzymes, or channelling, is a controversial topic, especially if the enzymes do not form a stable complex, i.e. ‘dynamic’ channelling [ 1-41. The level of passion aroused by discussions of metabolite channelling reflects a belief, not always explicitly stated, that if it occurs then it must have major metabolic consequences [ 51. V...
متن کاملMetabolite Channelling and Metabolic Complexity Substrate channelling in 2-0x0 acid dehydrogenase multienzyme complexes
Heteronuclear NMR spectroscopy and other experiments indicate that the true substrate of the E l component of 2-0x0 acid dehydrogenase complexes is not lipoic acid but the lipoyl domain of the E2 component. E l can recognize the lipoyllysine residue as such, but reductive acylation ensues only if the domain to which the lipoyl group is attached is additionally recognized by virtue of a mosaic o...
متن کاملStromal concentrations of coenzyme A and its esters are insufficient to account for rates of chloroplast fatty acid synthesis: evidence for substrate channelling within the chloroplast fatty acid synthase.
Concentrations of total CoAs in chloroplasts freshly isolated from spinach and peas were 10-20 microM, assuming a stromal volume of 66 microl per mg of chlorophyll. Acetyl-CoA and CoASH constituted at least 90% of the total CoA in freshly isolated chloroplasts. For a given chloroplast preparation, the concentration of endogenous acetyl-CoA was the same when extractions were performed using HClO...
متن کاملThe large subunit of the fatty acid oxidation complex from Escherichia coli is a multifunctional polypeptide. Evidence for the existence of a fatty acid oxidation operon (fad AB) in Escherichia coli.
The subunit locations of the five enzymes associated with the fatty acid oxidation complex from Escherichia coli were studied by immunotitration and chemical modification. Antibodies raised against the purified complex caused the parallel inhibitions of enoyl-CoA hydratase and 3-hydroxyacyl-CoA dehydrogenase, while slightly stimulating 3-ketoacyl-CoA thiolase. All five component enzymes of the ...
