  • Patent number: 9951362
    Abstract: The present invention relates to mutated and/or transformed microorganisms for the synthesis of various compounds. More specifically, the present invention discloses microorganisms mutated in the genes encoding for the regulators ArcA and IclR. The latter mutations result in a significant upregulation of the genes that are part of the colanic acid operon. Hence, said microorganisms are useful for the synthesis of any compound being part of the colanic acid pathway such as GDP-fucose, GDP-mannose and colanic acid, and/or, can be further used—starting form GDP-fucose as a precursor—to synthesize fucosylated oligosaccharides or—starting from GDP-mannose as a precursor—to synthesize mannosylated oligosaccharides. In addition, mutations in the genes coding for the transcriptional regulators ArcA and IclR lead to an acid resistance phenotype in the exponential growth phase allowing the synthesis of pH sensitive molecules or organic acids.

  • Patent number: 9914757
    Abstract: Provided is a methionyl tRNA synthase (MRS) for the biosynthesis of a photomethionine-labeled protein and a method for preparing a photoactivatable protein G variant using same and, more particularly, to an MRS variant in which alanine at the position of 12th is substituted with glycine, leucine at the position of 13th by serine, tyrosine at the position of 260th by phenylalanine, isoleucine at the position of 297th by valine, and histidine at the position of 301st by leucine from the N-terminal of the amino acid sequence of a wild-type Escherichia coli methionyl tRNA synthase. The MRS variant effectively confirms the biosynthesis of a photomethionine (pM)-labeled target protein and thus can be utilized for the biosynthesis of a pM-labeled target protein.
