Abstract:
Provided are polynucleotides and polypeptides involved in the biosynthesis of pamamycin and pamamycin precursors as well as vectors and recombinant microorganisms comprising the polynucleotides and polypeptides. Also provided are methods for the production of pamamycins, in particular pamamycin 607 and pamamycin 621, and their precursors.
Abstract:
The present invention relates to a method for recovering a protein of interest from a fermentation broth by adding a salt of a divalent cation and increasing the pH.
Abstract:
The present invention is directed to a method of purifying a protein of interest from the particulate matter of a fermentation broth comprising the step of purifying the protein of interest from the particulate matter of the fermentation broth, wherein the step of purifying the protein of interest from the particulate matter of the fermentation broth comprises one or more washing steps, which comprises contacting the particulate matter with a washing solution comprising one or more conditions that favor the solubilization of the protein of interest and/or the desorption of the protein of interest from the particulate matter.
