Question:

Can anybody tell me what is this ( Xenopus magainins )?


Answers: I just did a quick search in Yahoo, and apparently the Magainins is the class of antimicrobial peptide from the Xenopus skin (an African frog).
PubMed.com says:

"A family of peptides with broad-spectrum antimicrobial activity has been isolated from the skin of the African clawed frog Xenopus laevis. It consists of two closely related peptides that are each 23 amino acids and differ by two substitutions. These peptides are water soluble, nonhemolytic at their effective antimicrobial concentrations, and potentially amphiphilic. At low concentrations they inhibit growth of numerous species of bacteria and fungi and induce osmotic lysis of protozoa. The sequence of a partial cDNA of the precursor reveals that both peptides derive from a common larger protein. These peptides appear to represent a previously unrecognized class of vertebrate antimicrobial activities." Source(s):
