The two-layer circuit allows Escherichia coli to selectively utilize target substrates in a mixed pool; channel metabolic resources to growth by delaying enzymatic conversion until nutrient depletion; and activate, terminate, and re-activate conversion upon substrate availability.
To analyse the differences between centres in achieving a renal transplant, we estimated the percentage of patients activated on the waiting list who received a renal transplant within two years of being activated (conversion efficiency).
The enzyme PLAU is required for the normal repair of wounds originating on skin [ 104] and, as stated earlier, S. uberis can activate the conversion of PLAU to plasmin [ 23].
The unusually high level of 7-hydroxymethyl chlorophyll suggests that the excess GFP-BC proteins or the excess chlorophyll b might activate the conversion between chlorophyll a and b [ 15].
It activates the conversion of kininogen to bradykinin, which is also a powerful vasodilator.
The kallikrein-kinin cascade, also referred to as the "contact activation pathway" or intrinsic pathway, is initiated when factor XII (Hageman factor) binds to damaged tissue, becoming activated through conversion to factor XIIa. Factor XIIa converts prekallikrein to plasma kallikrein, and these two proteins autoactivate each other through a positive feedback loop.
SKN forms a 1 1 stoichometric complex with either plasminogen or plasmin, and in a host species-specific manner activates the conversion of plasminogen to plasmin a serine protease that can degrade fibrin clots and the extracellular matrix.
Typically in this process, phosphorylated sugar molecules are first activated by conversion into nucleotide sugar derivatives.
Once sulfate is transported in the cell, it is activated by conversion into adenosine 5'-phosphosulfate (APS) and 3'-phosphoadenosine 5'-phosphosulfate (PAPS).
Instead, local thermal motion of highly stretched noncrystalline chains may be activated, and the conversion from very taut noncrystalline chains to a crystalline phase may be easier because of smaller intermolecular distances and enhanced cohesive forces.
A key step for the generation of such objects is their dissymmetric modification with a catalyst particle that activates the chemical conversion of a fuel molecule, leading ultimately to the propulsion of the object.
