Pentapeptide, AAAAA, GGGGG, SSSSS, and YYYYY were synthesized by Hangzhou Kevin Biology, using alanine, glycine, serine and tyrosine as substrates, respectively.
(1999) The endogenous sulfated
pentapeptide phytosulfokine-a stimulates tracheary element differentiation of isolated mesophyll cells of zinnia.
Lipases also share a consensus
pentapeptide sequence of Gly-X-Ser-X-Gly motif, whereby X may be any amino acid residue [14].
There are two regulatory characteristics of ampR: in the absence of a [beta]-lactam inducer, it binds to the UDP-MurNAc
pentapeptide to promote the formation of an AmpR-DNA complex that represses ampC transcription, while in the presence of a [beta]-lactam antibiotic, peptidoglycan fragments accumulate in the cytoplasm [10], and the 1,6-anhydro-MurNAc tripeptide (or
pentapeptide) competitively displaces the UDP-MurNAc
pentapeptide and converts AmpR into an activator, triggering the ampC expression or production of [beta]-lactamase [9].
maltophilia has identified a novel family of resistance genes (smqnr) encoding proteins containing
pentapeptide repeats, which confer low-level resistance to quinolones (10).
The RUNX2 mutation resulted in the absence of the NMTS domain and C-terminal
pentapeptide VWRPY.
It can effectively inhibit the secretion of gastric acid caused by histamine,
pentapeptide gastrin, and the stimulation of food and reduce the activity of pepsin.
Cilcane is a
pentapeptide drug with an excellent safety profile and a novel mechanism of action compared to existing myeloma treatments, Research suggests the product will be synergistic in combination with a proteasome inhibitor, a class of drug normally given as a front line treatment for this disease and that this approach can also be extended to the treatment of other cancers, including breast cancer.
