A catalytic mechanism is the sequence of elementary reactions by which a catalytic reaction proceeds. The behaviour of nanoconfined water can be very different from that of the bulk and is ...

A 5.5 Å electron density map of ribonuclease has been obtained by X-ray diffraction using five isomorphous derivatives. One of the cystine residues is identified by means of a chemically modified ...

The mechanism of action underlying ketamine’s rapid antidepressant effects in patients with depression, both suffering from major depressive disorder (MDD) and bipolar disorder (BD), including ...

NNRTIs bind to a hydrophobic pocket near the catalytic site of HIV-1 RT and inactivate enzymatic activity. NNRTI-resistance mutations & their mechanism ... and an RNase H domain.

"The addition of water alters the reaction mechanisms, promoting pathways that enhance catalytic activity while suppressing coke formation," explains Dr. Ro. "This dual role improves process ...

This is where DNA and RNA epigenetics come in: a series of mechanisms that act as "markers" on genes, to control their activity without modifying the DNA or RNA sequence itself. Until now ...

This article will review the mechanisms of activation of alternative, classical, and lectin pathways, the formation of C3 and C5 convertases, the action of anaphylatoxins, and the ...
