The subject invention relates to a low cost method of producing peptides, including antimicrobial peptides (AMPs), by using microbes. The subject methods enable greatly improved yields of the peptide/AMP as compared to those heretofore known in the art. The subject methods also surprisingly enable the use of Pseudomonas fluorescens to produce AMPs and other peptides. There are several components of the subject invention, which can be used alone or in combination. The subject invention provides for the production of peptides/AMPs in concatemeric precursors. The subject invention also provides novel methods of assembling monomers into multimers, and of cleaving the multimers to yield active monomers. The subject invention also relates to the use of these multimers fused to carrier peptides to produce fusion proteins. Preferably, both the multimers and the fusion proteins (multimers with the carrier polypeptides) lack charge balancing. It has been surprisingly determined that it is not necessary to offset the positive charges of multiple copies of AMPs in multimeric constructs. Thus, the subject invention enables the use of a wider range of multimers and carrier peptides.

L'invention concerne une méthode bon marché de production de peptides, y compris des peptides antimicrobiens (AMP), à partir de microbes. La méthode de l'invention permet d'améliorer considérablement les rendements des peptides/AMP, par comparaison avec les méthodes antérieures connues. La méthode de l'invention permet curieusement d'utiliser Pseudomonas fluorescens pour produire des AMP et d'autres peptides. Plusieurs éléments de l'invention peuvent être utilisés seuls ou en association. L'invention concerne la production de peptides/AMP dans des précurseurs concatémériques. Elle concerne également de nouvelles méthodes d'assemblage de monomères en multimères, et de clivage des multimères pour produire des monomères actifs. L'invention concerne aussi l'utilisation de ces multimères fondus avec des peptides de support pour produire des protéines hybrides. De préférence, tant les multimères que les protéines hybrides (multimères comportant les polypeptides de support) manquent d'équilibrage de charge. L'on a découvert, de manière surprenante, qu'il n'est pas nécessaire de décaler les charges positives de multiples copies d'AMP dans des constructions multimériques. Les méthodes de l'invention permettent ainsi d'utiliser une gamme plus étendue de multimères et de peptides de support.
