In all enzyme structures obtained from pyruvate-soaked crystals, we observed well-defined electron densities consistent with a pyruvate molecule in a surface loop close to the entrance of the ...

Research has recently uncovered a crucial step in the telomerase enzyme catalytic cycle. This catalytic cycle determines the ability of the human telomerase enzyme to synthesize DNA. Research from ...

The researchers determined that a histidine amino-acid residue (His23) in BH32 forms an intermediate called an acyl–enzyme compound during the catalytic cycle. This intermediate is then ...

With this as a model, Agarwal's team theorized that it should be possible to improve the catalytic efficiency of enzyme reactions by attaching chemical elements on the surface of an enzyme and ...

The enzymes can convert up to 10,000 hydrogen molecules per second. More information: Martin Winkler et al. Accumulating the hydride state in the catalytic cycle of [FeFe]-hydrogenases ...

Pellows et al. use electron paramagnetic (EPR) spectroscopy to characterize photocatalytic E-state intermediates in the catalytic cycle of MoFe protein of the nitrogenase enzyme. Illuminating CdS ...
