Title: A Closer Look at Inventor Koji Yanai

Introduction

Koji Yanai, an accomplished inventor based in Odawara, Japan, has made significant contributions to the field of biotechnology. With 18 patents to his name, Yanai's work primarily revolves around the development of methods and tools that enhance the production of valuable biopharmaceuticals and enzymes.

Latest Patents

Yanai's recent innovations include a groundbreaking patent related to the UK-2 biosynthetic gene and a method for improving UK-2 productivity. This invention involved an in-depth analysis of the genomic DNA of *Streptoverticillium* sp. 3-7, which is known for its production of UK-2. The research successfully identified and isolated a region thought to contain the UK-2 biosynthetic gene cluster. By disrupting the genes in this region, a strain was created that failed to produce UK-2, thus confirming the genomic segment's role in the biosynthesis. Furthermore, the strain was transformed with a vector containing the isolated gene cluster, resulting in a productivity increase of 10 to 60 times compared to the parental strain, revealing the presence of two copies of the biosynthetic gene cluster per cell in the transformants.

In addition to this, Yanai has developed a method for producing horseradish peroxidase recombinant protein using filamentous fungi. This involved a modified polynucleotide with an altered base sequence that matches the codon usage frequencies of filamentous fungal species, enabling effective expression of the horseradish peroxidase polypeptide.
