repeat region and N-terminal half of hydrophobic region of prion protein (PrP) mediates PrP-dependent activation of superoxide dismutase.
Condensation of DNA and chromatin by an SPKK-containing octapeptide
repeat motif present in the C-terminus of histone H1.
The resulting octapeptide
, angiotensin II (Ang II), binds to transmembrane receptors and initiates several signaling pathways, including initiating the release of aldosterone from the adrenal gland.
Within the enzyme cascade of the renin-angiotensin system, ACE removes histidyl-leucine from angiotensin I to form the physiologically active octapeptide
angiotensin II, one of the most potent vasoconstrictors known.
Angiotensin-converting enzyme converts the inactive decapeptide, angiotensine I to the active octapeptide
and potent vasoconstrictor angiotensin II, which is the main product of the renin-angiotensin system (RAS) .
Antinociceptive action of Cholecystokinin octapeptide
(CCK) and related peptides in rats and mice: effects of naloxone and peptidase inhibitors.
In the group of orally infected squirrel monkeys, 3 had a unique heterozygous genotype that encoded either 4 or 5 octapeptide
Syntocinon is the synthetic form of octapeptide
However, antigens occur in countless shapes and forms as there are multiple ways to generate an octapeptide
(the length of peptide antigens held in the MHC binding groove).
The N-terminal domain is composed of five octapeptide
repeats that are rich in proline and glycine, the first of which is termed a "pseudorepeat" because it lacks histidine.
25, Boots Contains 'Inhibox' to freeze, tighten and smooth expression wrinkles, plus the wrinkle-relaxing octapeptide
'Snap-8' to minimise any muscle movement.
Other peptides such as tripeptide and octapeptide
complement the effects of Argireline and Matrixyl to minimize fine lines, decrease wrinkle depths and provide overall smoother, younger looking skin.
