There is a substantial substrate-dependent difference in aptamer signal, with the UltraGAPS giving a much higher signal than the other substrates.
The N- R -epoxypropyl aN- R -epoxypropyled poteN- R -epoxypropyldulanalogcompared to DAPT and showed substantial substrate selection for APP cleavage over Notch cleavage, while N-(2-fluoro)benzyl analog 10c showexhibitedst potent γ-secretase inhibition with dull selectivity.
Regarding the fabrication processes, the central parameters of droplet etching which differ from droplet epitaxy involve a low group V flux to avoid crystallization of the droplets, as well as higher temperatures allowing substantial substrate etching and material removal.
The most striking feature is, however, the occurrence of substantial substrate cycling within the C3/C4 inter-conversions upon growth on methanol.
Nevertheless, substantial substrate cycling could be measured within C2/C3/C4 inter-conversions, indicating that the metabolic network is highly versatile around a flexible backbone of central reactions that allows rapid switching to multi-carbon sources.
In such experiments it is simplest to measure the rate of conversion of substrate to product over the early time points, before substantial substrate depletion has taken place, as later measurements may underestimate enzyme velocity.
Structural data suggest that domain 2 of the protease possesses substantial substrate binding pockets which form the bulk of the interactions with the NS boundaries and largely dictate boundary specificity and cleavage.
In murine RFC, replacement of Ser (homologous with Ser in hRFC) with phenylalanine resulted in loss of transport and MTX resistance, although the transport phenotype showed substantial substrate dependence [ 18].
In contrast, compounds with substantial substrate-envelope violations had poor specificity profiles.
Despite the lack of perturbation of the iron sulfur cluster EPR signals in the presence of tyrosine, there was a substantial loss in substrate binding affinity in the variant proteins.
There was a corresponding reduction in β phase fraction and a substantial reduction in the substrate aluminized layer thickness.
