  • Patent number: 8586336
    Abstract: A novel xylose isomerase nucleotide sequence obtained from a bovine rumen fluid metagenomic library and also provides the amino acid sequence encoded by the nucleotide sequence, and a vector and a transformant containing the nucleotide sequence. When the xylose isomerase is expressed, a host cell is endowed with the capability of converting xylose into xylulose, and the xylulose is further metabolized by the host cell. Therefore, the host cell can take the xylose as a carbon source for growth. The xylose isomerase from a new source is expressed with high activity in Saccharomyces cerevisiae and is a mesophilic enzyme with optimal temperature of 60° C.
