This laboratory is responsible for the undergraduate and graduate education in industrial biotechnology and biomolecular engineering. Our research focuses on engineering of functional proteins, such as enzymes and antibodies, enzymatic synthesis of bioactive compounds, as well as high-throughput screening of transcription factor binding sites in the genomes of microorganisms, plants and animals. In a quest for highly efficient and specific functional proteins, we utilize traditional protein engineering methods in combination with computational analysis of protein structure and dynamics, and our specialized technology for high-throughput screening of large random DNA-protein libraries.

The following research projects are currently in progress:

Development and application of Beads display technology (coding DNA and corresponding protein are linked and displayed on the surface of the microbeads) for various purposes such as high throughput screening of random libraries in directed evolution of enzymes (horseradish peroxidase, manganese peroxidase, cytochrome P450, transglutaminase) and comprehensive analysis of transcription factor binding sites.
  2. Development of high-throughput screening system for monoclonal antibodies using single-cell RT-PCR and the cell-free protein synthesis (CFPS). Recently, we have succeeded in producing soluble and fully functional Fab fragments in E. coli CFPS system by fusing the Fab with Leucine zipper.
  3. Cloning, expression and protein engineering of lipid-modifying enzymes such as phospholipase D, lipase, and phosphatase to obtain enzymes with novel functions or improved activities.

Glycan chains are covalently attached to proteins and lipids to form glycoproteins and glycolipids, i.e., “glycoconjugates”, and cover the entire surface of cells in any bioorganisms on our planet. They play important roles in a myriad of biological processes, such as cell adhesion, tissue and organ formation, and host recognition to pathogens or symbionts. In most cases, they play roles in various cell societies. However, there are still many glycan chains that remain to be elucidated for their biological functions. Thus, our research goal is to understand how glycan chains function on the cell surface as well as soluble glycoconjugates.

Two projects are going on in our laboratory:

(1) Glyco-atmosphere, a field of glycans on the surface of cells and glycoconjugates: Demonstration of its existence and biological significance;
(2) Diversity and heterogeneity of sialic acids and polysialic acids: Their structure, biosynthesis, function, and applications.
Glycobiology, our research field, is relatively young and challenging, but has become more and more important as a leading area of biological sciences, especially in the current post-genomic era.

Microtubule network in spherical hepatocytes

The human health is closely related with the metabolic conditions, which is greatly affected by nutrition. In this lab, we are investigating the nutritional regulation of energy and protein-amino acid metabolism. It has been recently elucidated that branched-chain amino acids (BCAA) have great effects on the protein and glucose metabolism.
How can liver, a metabolic center organ, keep hepatocyte-phenotype? We have found that cultured hepatocytes with spherical cell shape can keep high levels of liver specific phenotype and that some liver-enriched transcription factors such as HNF-4. We are now focusing our effort on 1) identification of a regulatory transcription factors controlling HNF-4 by cell shape and 2) molecular mechanism of signal transduction pathway from cell shape to nucleus. Recently we are also trying to establish artificial liver support system by using spherical human hepatoma cells.

Current projects are follows:

  1. Nutritional regulation of gene expression in animals.
  2. Molecular mechanism of hepatocytes differentiation of 3-dimentional culture.
  3. Physiological significance of liver clock.
  4. Regulatory mechanism for the BCAA catabolism.
  5. Regulation of glucose metabolism by BCAA.

Filamentous fungi produce high level of polysaccharide-degrading enzymes and are frequently used for production of industrial enzymes. Because of the outstanding capacity for protein secretion, filamentous fungi are desirable industrial microorganisms for production of both intrinsic and foreign proteins.

Research projects are now in progress in the following areas aiming industrial application in near future:

  1. Regulation of amylolytic, cellulolytic, and xylanolytic genes in Aspergillus species. Analysis of various transcription factors, including AmyR, XlnR, AraR, Hap complex, and more, is now in progress by molecular biological approach.
  2. Signal transduction systems, especially His-Asp phosphorelays, in Aspergillus species. In response to environmental conditions, filamentous fungi change morphology, life cycle, enzyme production, etc. We are focusing on still-uncharacterized sensor proteins to solve complex signal transduction networks.

Research at the laboratory aims at better understanding the ways plants and algae acquire energy, carbon, and nitrogen. It seeks to understand the events involved, in terms of basic mechanism, and to discover the ways they are integrated and regulated so as to determine the response of the photosynthetic organisms to different physical and chemical environments.

The research projects focus on the areas of plant biochemistry, molecular biology, and physiology and the followings are now in progress;

  1. The nature and regulatory processes of photosynthetic carbon dioxide fixation and nitrogen assimilation.
  2. Structure and expression of genes encoding enzymes or proteins involved in photosynthetic carbon and nitrogen metabolisms.
  3. Regulatory mechanisms of nitrogen-dependent gene expression for enzymes in carbon and nitrogen assimilation in plants and cyanobacteria.
  4. Enzymology and regulatory mechanisms of chlorophyll biosynthesis in photosynthetic organisms.
