The gibberellin stimulated-like (gsl) or snakin peptides from higher plants are cysteine-rich, with broad spectrum activity against a range of bacterial and fungal pathogens to detect gsl peptides in applications such as western blot analysis and enzyme-linked immunosorbent assays (elisa), specific. Expression and purification of the recombinant murine reg3α protein in pichia pastoris and characterization of its antimicrobial and antitumour efficacy kuohai fan department of clinical medicine, college of animal science and technology, shanxi agricultural university, taigu, shanxi, china. A process was developed for expressing antimicrobial peptides in a recombinant host cell that eliminates host cell toxicity and antimicrobial peptide degradation, as well as providing a process for rapid purification.
Large-scale expression and purification bl21-og2-intein2 was cultured in 1l medium and induced with 01 mm iptg at 30°c for 2 h the soluble og2-intein2 protein accounted for 127% of the total soluble protein in the supernatant ( figure 4(a) , lane sp. B bommarius et al / peptides 31 (2010) 1957-1965 1959 fig 1 (a) schematic outline of the cloning strategy for in frame translation of the fusion product sumo-peptide. Human histatin 1 (hst1), a member of the histatin family, possesses antimicrobial properties in this study, we applied a previously developed cleavable self-aggregating tag (csat) for the expression and purification of histatin 1 to demonstrate its utility for peptide expression and purification. The production and purification of dcd-1l using sumo tag compare advantageously to other protocols previously described thus, the sumo tag system enables large scale recombinant production of the antimicrobial peptide dcd-1l, which constitutes pharmaceutical and therapeutic potential as an alternative antibiotic. In summary, this work presents an expression and purification method that can be applied to the production of the human anionic antimicrobial peptide dermcidin in bacteria the above results showed that his6x-smt3-dcd-1l protein expression system was able to circumvent the toxicity of dcd-1l on the host cells and simplify the peptide.

Abstract the antimicrobial peptide cm4 is a 35-residue cationic peptide to explore a new approach for the expression and purification of cm4 in escherichia coli, the cm4 gene was cloned into the vector pet32a to construct an expression vector pet32a-cm4. Several fusion strategies have been developed for the expression and purification of small antimicrobial peptides (amps) in recombinant bacterial expression systems. Read expression and purification of the antimicrobial peptide cecropin ad by fusion with cationic elastin-like polypeptides, protein expression and purification on deepdyve, the largest online rental service for scholarly research with thousands of academic publications available at your fingertips.
High-yield soluble expression and simple purification of the antimicrobial peptide og2 using the intein system in escherichia coli. In this paper, we have used hg31p as a novel fusion protein for the expression and purification of p-113 the purity of the expressed p-113 is more than 95% and the yield is 4 mg p-113 per liter of e coli cell culture in luria-bertani (lb) medium. The intrinsic antimicrobial activity of antimicrobial peptides may prevent their expression in e coli however, several proteins and peptides have been shown to be successful as fusion partners with antimicrobial peptides to enable their expression in e coli [ 20 - 22 . Magainin-2 (mag2) is a polycationic antimicrobial peptide isolated from the skin of the african clawed frog xenopus laevis it has a wide spectrum of antimicrobial activities against gram-positive and gram-negative bacteria, fungi, and induces osmotic lysis of protozoa.
