As known from literatures [19, 30], the SERS effects depend strongly on the roughness of the metal nanostructure used as the substrate; we could expect that these three nanostructures would definitely enhance the SERS spectra.
As 2-OG acts as a co-substrate, we could then apply this assay to examine the enzyme kinetics of FTO with regards to its usage of 2-OG, arriving at a 2-OG Km value for FTO of 2.88 μmol/l.
Most of these (345) link tyrosine phosphatases to their substrates, while we could only recover information about 35 dephosphorylation reactions mediated by PPPs.
Thus, by adjusting the concentration of zinc nitrate, temperature, reaction time, and substrate patterning we could control the most important characteristics of anisotropic crystallization process: that is, location, density, and anisotropic crystallographic orientation.
Using this inhibitor and the continuous measurement of substrate processing, we could demonstrate that the assay has a signal-to-noise ratio (S/N) of 300 and an almost perfect Z' factor (Figure 2A).
(With higher substrate concentrations, we could avoid the sample handling problem by assaying the same volume of each dilution, but the same approach with more dilute substrate would yield samples with no counts).
So far, the data presented supported the possibility that DDX3X is a novel TBK1 substrate, although we could not formally exclude the presence of an intermediate kinase activated by TBK1.
Using a structural model, we were able to identify a glutamate residue (Glu324) that is crucial for substrate binding, and we could alter the substrate specificity by protein engineering.
I think when we discovered that the aggregate-prone proteins that cause neurodegenerative diseases are autophagy substrates, and that we could enhance their removal by upregulating autophagy.
