To further demonstrate the feasibility of applying Hsp104 to reversing disease in humans, it will be essential to develop substrate-optimized Hsp104 variants to avoid off-target effects.
These different effects on Sirt1 activity against different substrates, as observed for resveratrol (see the Discussion section), might indicate the exciting possibility to develop substrate-specific modulators for Sirt1.
Rather, we should pursue our work and gather a better understanding of the basic cell biology of γ-secretase in order to develop substrate-specific inhibitors or modulators that produce, for instance, shorter Aβ peptides without affecting the Notch pathway.
The results clarify the newly developed substrate mimetics as efficient acyl donors as well as BL-GSE as an attractive alternative to V8 protease for enzymatic peptide synthesis.
The sub-C size cylindrical sealed cell using the developed substrate exhibited superior high-rate discharging capability to the cell using the foam-type one in spite of the reduction in the amount of plated nickel due to the characteristic three-dimensional micronetwork structure of the developed substrate.
Tetramethyl benzidine (TMB; Pierce, Rockford, IL) was the color developing substrate and the readings were done at 450 nm.
Since AtCRT1a and CRT1b do not seem to be predominantly involved in the folding of the EFR (Figures 9; [27]), it is apparent that the different subgroups of CRTs have developed substrate specificity.
Plates were washed and developing substrate (Mabtech) was added.
Finally, the membranes were incubated for 30 min in Sigma-Fast 3,3′-diaminobenzidine developing substrate (Sigma-Aldrich) and then rinsed in distilled water.
Diaminobenzidine (DAB Peroxidase Substrate Kit, Vector Laboratories, Burlingame, VT, USA) was used as the developing substrate leading to a brownish color of the immunopositive cells.
