Arginine-rich cell-penetrating peptides.
Arginine-rich cell-penetrating peptides are short cationic peptides capable of traversing the plasma membranes of eukaryotic cells. While successful intracellular delivery of many biologically active macromolecules has been accomplished using these peptides, their mechanisms of cell entry are still under investigation. Recent dialogue has centered on a debate over the roles that direct transloc...
متن کاملArginine-rich peptides and their internalization mechanisms.
As the versatility and use of CPPs (cell-penetrating peptides) as intracellular delivery vectors have been widely accepted, the cellular uptake mechanisms that enable their efficient internalization have become the subject of much interest. Arginine-rich peptides, including HIV-1 Tatp (transactivator of transcription peptide), are regarded as a representative class of CPPs. Evidence suggests th...
متن کاملTryptophan-rich antimicrobial peptides: properties and applications
There is a world-wide quest for development of new-generation antibiotics, due to the emergence of microbial pathogens that have developed resistance to the currently available antibiotics. The antimicrobial peptides (AMPs) are a strong candidate in this regard, due to minimal possibilities of emergence of resistance against these. The tryptophan (Trp)-rich peptides comprise an important class ...
متن کاملStructural variety of arginine-rich RNA-binding peptides.
Arginine-rich domains are used by a variety of RNA-binding proteins to recognize specific RNA hairpins. It has been shown previously that a 17-aa arginine-rich peptide from the human immunodeficiency virus Rev protein binds specifically to its RNA site when the peptide is in an alpha-helical conformation. Here we show that related peptides from splicing factors, viral coat proteins, and bacteri...
متن کاملArginine-rich self-assembling peptides as potent antibacterial gels.
Hydrogel materials that display inherent activity against bacteria can be used to directly treat accessible wounds to prevent or kill existing infection. Hydrogels composed of self-assembling β-hairpin peptides, having a high content of arginine, were found to be extremely effective at killing both gram-positive and gram-negative bacteria, including multi-drug resistant Pseudomonas aeruginosa. ...
