  • Riboflavin synthesis in yeast
    Patent number: 6929933
    Abstract: The invention describes the riboflavin biosynthesis gene and gene products from yeast. Vectors and recombinant preparation processes for riboflavin are furthermore described. Specifically, the invention relates to the genes for riboflavin biosynthesis in yeast, the proteins encoded therewith and genetic engineering process for the preparation of riboflavin using these genes and gene products. Accordingly, six genes (rib genes), which encode from enzymes of riboflavin biosynthesis starting from GTP, were found in the yeast Saccharomyces cerevisiae and isolated.

  • Orotidine-5?-phosphate decarboxylase-gene, gene construct containing said gene and the utilization thereof
    Patent number: 6927026
    Abstract: The invention relates to an orotidine-5?-phosphate decarboxylase gene having the sequence of SEQ ID NO: 1 or its homologs, to a gene construct comprising this gene or its homologs, and to its use. The invention additionally relates to vectors or organisms comprising an orotidine-5?-phosphate decarboxylases gene having the sequence SEQ ID NO: 1 or its homologs. The invention further relates to a process for producing uracil-auxotrophic microorganisms and to a process for inserting DNA into uracil-auxotrophic microorganisms.
