Project Title: STUDIES ON GENE STRUCTURE AND FUNCTION: CLONING, SEQUENCING, EXPRESSION AND MODIFICATION OF SELECTED GENES FROM BACTERIA AND FUNGI

Molecular biotechnology has become the core technology for many areas of research and application in biotechnology. It has been developed from research in molecular biology on the investigation on living processes at the gene and protein levels. This project will study the structure and function of several selected genes from bacteria and fungi which are of interest in animal and plant diseases and industrial biotechnology.

The studies will involve cloning and sequencing of the genes, identification of their structural and regulatory elements, and prediction of the amino acid sequence of the corresponding proteins. The cloned genes will be expressed and the product investigated via molecular and biochemical techniques to define their functional domains. The results will contribute towards further understanding of the structure and function of proteins of the type chosen for these studies.

The project will enhance the present expertise in gene cloning and sequencing and will develop new expertise in optimization of expression and production of recombinant proteins in bacteria and yeasts. The studies on functional domains will build up expertise on protein modification and engineering. The project is a collaborative effort by 10 principal researchers in biochemistry, microbiology and molecular biology from UKM, USM and UPM. As a group, the researchers have the necessary expertise and experience to execute the project. The participating laboratories have adequate and complementary facilities for studies of genes and proteins. At the appropriate times, reputable researchers in molecular biology from established research institutions abroad will be invited to review the progress and direction of the project.

 

 

Achivement

  • Gene Structure: The sequence of some of the target genes (the metalloprotease gene, the cutinase gene, the mutant ilvB genes, and an amplified product of the thermophillic protease gene) have been determined. The controlling elements of one of the gene (cutinase) have been identified.
  • Gene FuncHon: Some of the genes (the serine protease gene, the alkaline protease gene) have been expressed and their activities are similar to the corresponding native enzymes. The structural principles underlying the specific functions of the enzymes are subjects of longer - term studies.
  • Know-how: The know-how targeted for are: gene cloning and sequencing, optimisation of expression of recombinant proteins, structural determination via homology modelling, X-ray crytallography and protein engineering. Know-how in gene cloning and sequencing and structural determination by homology modelling, have been established. Know-how in optimisation of expression has been partly established. The other technologies will be employed in further studies.

Benefit of the Project
