... the inhibitory function on molting has been demonstrated convincingly. Most biological assays of the gonad inhi- bition of this neuropeptide rely on its ability to inhibit ovary development and reduce ... 120 h after injection (Figs 4A and 5A). In conclusion, the use of recombinant protein or RNAi alone may not be sufficient to confirm the func- tion of a neuropeptide. The c...

In conclusion, the combination of these results shows that residues R97 and Y331 modulate the ionization of residue E399 by stabilizing its charge and reducing its pK a , ... clearly increased. Actually, the substitution of R97 by methionine or lysine resulted in the same increment in the pK a of E399 (Table 2). Therefore, M97 and K97 a...
