The real buzz in recent months, however, has been around something called pentapeptides
, a group of amino acids that renew the skin's outermost layer and help eliminate wrinkles.
Elastin-like polypeptides (ELPs) are biopolymers composed of the pentapeptide
repeats Val-Pro-Gly-Xaa-Gly (MW 51kD).
A long pentraxin-3-derived pentapeptide
for the therapy of FGF8b-driven steroid hormone-regulated cancers.
Vancomycin binds with high affinity to the D-Ala-D-Ala termini of the pentapeptide
precursor units, blocking their addition to the growing peptidoglycan chain and preventing subsequent cross-linking (44).
Qnr proteins belong to the pentapeptide
repeat family, which consists of uninterrupted pentapeptide
repeats comprising 92% of the sequence and play a role in DNA gyrase protection (7).
Peptides Plus Double-Action Wrinkle Reverse Creme and Serum from derma e Natural Bodycare contains high concentrations of two of the most powerful peptides available: palmitoyl pentapeptide
, marketed under the trade name Matrixyl, and acetyl hexapeptide, or Argireline.
Those demographics and other social trends, including the rise in popularity of such body-altering procedures as plastic surgery and botox injections and the popularity of expensive spa treatments, industry executives say, have given rise to "cosmeceuticals," which are marketed as over-the-counter personal care products and contain such active ingredients as alpha-hydroxy acid, creatine and pentapeptide
Pentagastrin is a synthetic pentapeptide
containing the carboxyl-terminal tetrapeptide, the active portion found in all natural gastrins.

Topical palmitoyl pentapeptide
provides improvement in photoaged facial skin.
The Ser-404 is not present in the usual pentapeptide
sequence G-X-S-X-G but in G-D-S-L sequence.
It is mediated by a 218-aa protein, Qnr (lately termed QnrA), which belongs to the pentapeptide
repeat family of proteins that protects DNA from quinolone binding to topoisomerases (4,5).
