Abstract: Stabilized reverse transcriptase fusion proteins including a thermostable reverse transcriptase connected to a stabilizer protein are described. Attaching the stabilizer protein to the thermostable reverse transcriptase stabilizes the fusion protein and can aid in its purification, provide increased solubility, allow for longer storage, or allow the fusion protein to be used under more rigorous conditions such as higher temperature. The stabilized reverse transcriptase fusion protein can also include a linker between the stabilizer protein and the thermostable reverse transcriptase. The stabilized reverse transcriptase fusion proteins are suitable for use in nucleic acid amplification methods such as the reverse transcription polymerase chain reaction and other applications involving cDNA synthesis.

The present invention also provides methods for the production of L-serine or L-serine derivative using such genetically modified microorganisms.

Abstract: An object is to identify endoglucanase and ?-glucosidase genes by isolating genomic DNA containing cellulase genes, which are classified into endoglucanases or ?-glucosidases, from Acremonium cellulolyticus, and sequencing the nucleotide sequences thereof. The inventors intensively compared the amino acid sequences of known endoglucanases and ?-glucosidases with each other to find conserved region of amino acid sequences in Acremonium cellulolyticus, and various primers were designed based on the information. PCR was carried out using the various primers thus designed and genomic DNA or cDNA as a template. As a result, gene fragments of endoglucanases and ?-glucosidases were obtained. Primers were designed based on the gene fragments, and PCR was carried out to amplify nine genes of endoglucanases and ?-glucosidases. The nucleotide sequences thereof were sequenced, and the present invention was completed.
