Formation of Enzyme-Enzyme Heteroconjugates

Agricultural and Biological Chemistry, 1984
Enzyme-enzyme heteroconjugates of phosphoglyceromutase, enolase and pyruvate kinase, which sequentially act to produce ATP in the glycolytic pathway, were constructed with a bifunctional reagent, N-succinimidyl 3-(2-pyridyldithio)propionate. The conjugates of phospho-glyceromutase-enolase, enolase-pyruvate kinase and phosphoglyceromutase-enolase ...

Cyclic nucleotide specificity of the activator and catalytic sites of a cGMP-stimulated cGMP phosphodiesterase from Dictyostelium discoideum [PDF]

, 1985
The cellular slime mold Dictyostelium discoideum has an intracellular phosphodiesterase which specifically hydrolyzes cGMP. The enzyme is activated by low cGMP concentrations, and is involved in the reduction of chemoattractant-mediated elevations of ...

Enzyme Kinetics at High Enzyme Concentration

Bulletin of Mathematical Biology, 2000
We re-visit previous analyses of the classical Michaelis-Menten substrate-enzyme reaction and, with the aid of the reverse quasi-steady-state assumption, we challenge the approximation d[C]/dt approximately 0 for the basic enzyme reaction at high enzyme concentration.

Several lines of antioxidant defense against oxidative stress: antioxidant enzymes, nanomaterials with multiple enzyme-mimicking activities, and low-molecular-weight antioxidants

Archives of Toxicology
Reactive oxygen species (ROS) and reactive nitrogen species (RNS) are well recognized for playing a dual role, since they can be either deleterious or beneficial to biological systems.

Angiotensin-converting enzyme 2 is a functional receptor for the SARS coronavirus

Nature, 2003
Spike (S) proteins of coronaviruses, including the coronavirus that causes severe acute respiratory syndrome (SARS), associate with cellular receptors to mediate infection of their target cells. Here we identify a metallopeptidase, angiotensin-converting
