Adenoregulin is a 33 amino acid antibiotic peptide who belongs to dermaseptin family which is the first vertebrate family to show lethal effects against filamentous fungi, as well as a broad spectrum of pathogenic microorganisms. Synthetic adenoregulin gene was cloned in 2, 4 and 6 tandem repeats and subcloned in pET32a and pET22b vectors. Recombinant plasmids were transformed into E. coli BL21(DE3), Fusion proteins of Trx-ADR1, Trx- ADR2 and Trx-ADR4 could be expressed after the hosts were induced by IPTG, but the expression level decreased dramatically with the number of tandem repeats increased. ADR1, ADR4 and ADR6 could not be expressed by E. coli without carrier proteins. But for Pichia pastoris GS115, ADR1 and ADR6 in the fermentation broth of the hosts could be detected by ELISA, and the bactericidal activities could also be observed.

More about this publication?
  • Protein & Peptide Letters publishes short papers in all important aspects of protein and peptide research, including structural studies, recombinant expression, function, synthesis, enzymology, immunology, molecular modeling, drug design etc. Manuscripts must have a significant element of novelty, timeliness and urgency that merit rapid publication. Reports of crystallisation, and preliminary structure determinations of biologically important proteins are acceptable. Purely theoretical papers are also acceptable provided they provide new insight into the principles of protein/peptide structure and function.
