Abstract:
The present invention relates to nulceotide sequences encoding enzymatically active cobalamin-methionine synthase and functional fragments thereof being modified in comparison to the respective wild-type enzyme such that said enzymes show reduced product inhibition by methionine. The present invention also relates to polypeptides being encoded by such nucleotide sequences and host cells comprising such nucleotide sequences. Furthermore, the present invention relates to methods for producing methionine in host organisms by making use of suchnucleotide sequences.
Abstract:
The present invention relates to a method of increasing the amount of at least one polypeptide in the host cell by expressing a modified nucleotide sequence encoding for a polypeptide in a host cell with said modified.nucleotide sequence being derived from a different non-modified nucleotide sequence encoding for a polypeptide of identical amino acid sequence such that the codon usage of the modified nucleotide sequence is adjusted to the codon usage of abundant proteins in the host cell.
Abstract:
The present invention is directed to a method of reducing the amount of at least one polypeptide in a host cell by expressing a nucleotide sequence encoding for the polypeptide in the host cell wherein the nucleotide sequence uses codons that are rarely used according to the codon usage of the host organism. Furthermore, the present invention relates to nucleotide sequences encoding for a polypeptide with a codon usage that has been adjusted to use codons that are only rarely used according to the codon usage of the host organism. The present invention further relates to the use of such sequences and methods for producing fine chemicals such as amino acids, sugars, lipids, oils, carbohydrates, vitamins, cofactors etc.
