They code pentapeptide repeat proteins which inhibit the action of FQn against bacterial DNA gyrase and topoisomerase IV.5 Qnr genes are classified as QnrA, QnrB, QnrC, QnrD and QnrS which differ 70% or more on the basis of nucleotide sequence.6
It is to be noted that the photo-initiating efficiency dramatically decreases when A, G, or S is condensed into pentapeptide, respectively.
(1997) Phytosulfokine-[alpha], a sulfated pentapeptide, stimulates the proliferation of rice cells by means of specific high- and low-affinity binding sites.
These Smqnr proteins (QnrA, B and S) in which pentapeptide repeats could be found, confer low-level quinolone resistance by protecting DNA gyrase and topoisomerases.
The main PMQR genes circulating are qnrA, qnrB, qnrS and aac(6')-Ib-cr, which produce pentapeptide proteins capable to cause resistance to quinolones by protecting the antimicrobial target protein, type II DNA topoisomerases (RODRIGUEZ-MARTINEZ et al.
It delivers the same hero pentapeptide as the rest of the 3 Point range, and this time expect a turbocharged effect; it promises wrinkles look better after just one night.

One of these is a pentapeptide known as Pal-KTTKS, which is kept in a special box inside the laboratory, beyond our inexperienced hands.
On substrates it exposed to environment and conidia carried away by air (Shanthi & Vittal, 2010).D Asteromyces cruciatus produced pentapeptide lajollamide A, and compounds regiolone, hyalodendrin, gliovictin, N-norgliovicitin and bis-N-norgliovictin which have many biological activities and antimicrobial properties (Gulder et al., 2012).
Vancomycin also prevent the transfer and addition of the muramyl pentapeptide and minutely changes the permeability of cell wall of Gram-positive bacteria but is ineffective against Gram negative ones.

There is a lipase-like catalytic triad (serine, aspartic acid, and histidine residues) in the catalytic domain, as well as a signature sequence of a pentapeptide [Gly-Xaa-Ser-XaaGly] (where Xaa denotes any amino acid residue) known as the lipase box.
