Writing tools A collection of writing tools that cover the many facets of English and French grammar, style and usage.

Protein kinases are one of the largest protein alostsrica and they are responsible for regulation of a great number of signal transduction pathways in cells, through the phosphorylation of serine, threonine, or tyrosine residues. Picosecond dynamics of T and R forms of aspartate transcarbamylase: These enzymes are rather large enzymatic complexes usually composed of at least one catalytic subunit and a regulatory fraction, and the complex catalytic activity is given by the cooperative interactions between those enzymatic subunits.

Fractal kinetics and spatial segregation.

An allosteric effect is described as a variation in proteins activity through the interaction of another molecule at a site on the protein which is distinct from the “active” site. Allosteric enzymes function through reversible, noncovalent binding of a regulatory metabolite called a modulator. Deregulation of these enzymes is associated with several diseases including cancer, diabetes and inflammation.
