Kholodenko; Signalling over a distance: gradient patterns and phosphorylation waves within single cells. Biochem Soc Trans 1 October ; 38 5 : — Recent discoveries of phosphorylation gradients and microdomains with different protein activities have revolutionized our perception of information transfer within single cells. The different spatial localization of opposing reactions in protein-modification cycles has been shown to bring about heterogeneous stationary patterns and travelling waves of protein activities. We show how switches between low-activity and high-activity states in a bistable activation—deactivation cycle can initiate the propagation of travelling protein-modification waves in the cytoplasm. Typically, an activation wave is initiated at the plasma membrane and propagates through the cytoplasm until it reaches the nucleus. An increase in deactivator activity is followed by the initiation of an inactivation wave that moves in the reverse direction from the nucleus.

Artificial metalloenzymes have been recently established as efficient alternatives to traditional transition metal catalysts. The presence of a secondary coordination sphere in artificial metalloenzymes makes them advantageous over transition metal catalysts, which rely essentially on their first coordination sphere to exhibit their catalytic activity. Recent developments on streptavidin- and avidin-based artificial metalloenzymes have made them highly chemically and genetically evolved for selective organometallic transformations. In this review, we discuss the chemo-genetic optimization of streptavidin- and avidin-based artificial metalloenzymes for the enhancement of their catalytic activities towards a wide range of synthetic transformations. Considering the high impact in vivo applications of artificial metalloenzymes, their catalytic efficacies to promote abiological reactions in intracellular as well as periplasmic environment are also discussed.

Understanding the interplay of glutamate dehydrogenase 1 and MitoNEET

In contrast to the lead molecule, histamine, the new derivatives possessed higher affinity for three different CA isozymes, as evidenced by compairing the affinity constants of these compounds for isozyme CA II. All rights reserved. RSO2NH2, are widely used drugs for the treatment or prevention of a variety of diseases, such as: glaucoma, L2. In contrast to inhibitors,. CA-s play an important role in the animal, vegetal and bacterial kingdoms, in.

Metrics details. Chemotherapy is the main treatment for acute myeloid leukemia AML , but the cure rates for AML patients remain low, and the notorious adverse effects of chemotherapeutic drugs drastically reduce the life quality of patients. Penfluridol, a long-acting oral antipsychotic drug, has an outstanding safety record and exerts oncostatic effects on various solid tumors.

    Enzyme activators are molecules that bind to enzymes and increase their activity. They are the opposite of enzyme inhibitors. These molecules are often.
