• Recombinant protein purification from E.coli expression system
• Protein purity and homogeneity analysis
• Enzyme characterization
• Protein structure prediction and analysis

Who should attend

Postgraduate students (Master and PhD students), Post Doctorate, Academicians and Researchers (Government and non-government institution)

List of Speakers and Trainers

  • Associate Professor Dr. Ng Chyan Leong is a structural biologist. He completed his PhD in York Structural Biology Laboratory (YSBL), Chemistry Department, University of York, UK in 2007 under the supervision of Prof. Dr. Fred Antson. He then worked as a Postdoctoral Fellow in Dr. Venki Ramakrishnan’s group at the Medical Research Council, Laboratory of Molecular Biology (MRC-LMB), Cambridge, UK, focusing on ribosome and protein translation. He joined INBIOSIS in 2012 as a Research Fellow and has established the recombinant protein purification, protein crystallization and protein analysis platform in the Institute.

  • Assoc. Prof. Dr. Ng Chyan Leong’s research interests are to unveil the structure and function of conserved hypothetical proteins, secondary metabolites biosynthesis enzymes, toxin and epitope of allergen molecules. His group determines the atomic resolution protein structure using X-ray crystallography, and applies biochemistry, biophysics, molecular biology and bioinformatics for structural and functional analysis. Together with national and international collaborators, his group has determined the atomic resolution crystal structure of the human CZIB protein, house dust mite allergen, Hydra Actinoporin-Like Toxin (HALT), nerol dehydrogenase and thermophilic amylase, and characterized several secondary metabolites biosynthesis enzymes and proteins with unknown function. Dr. Ng’s research interest is also extended to understanding the impact of carbon sources (glucose vs triglyceride) in fungi metabolite biosynthesis, and plant alkaloid biosynthesis pathway using systems biology approaches, which may lead to the development of alternative microbial fermentation platform and drug discovery. His group has received various university and national research grants, and actively collaborates with industry partners. Their research output has been published in peer-reviewed indexed journals ( including Nature Communications, Scientific Reports, Plant Physiology and Biochemistry, Phytochemistry, Peer J and Microbial Cell Factories.

  • Please feel free to contact Dr. Ng ( for research and industrial projects collaboration. Research students are welcomed to join the group. 

  • Associate. Prof. Dr. Maizom Hassan obtained her Bachelor (1999), Masters (2004) and Ph.D. Degrees (2008) in Bioresources Science from the University of Tottori, Japan. After completing her studies, she was appointed as a Research Fellow/Senior Lecturer at the Institute of Systems Biology (INBIOSIS), Universiti Kebangsaan Malaysia (UKM). Her current research focuses on the development of biorational insecticide for oil palm pest management by using integrated systems biology, enzymology and entomology approaches. Her other research interests are purification and characterization of several microbial and plant enzymes. Her research interests were manifested in 2 patents, 1 book, 1 book-chapter and 29 publications which include 22 publications in high-impact journals such as Plants, Plant Physiology and Biochemistry, Insects, Phytochemistry, Genes and PloS ONE. Her publications attracted 153 citations with h-index of 8.

  • Associate. Prof. Dr. Maizom has been instrumental in establishing industry collaboration with Sime Darby, the largest listed palm oil company globally, Felda Global Ventures R&D Sdn. Bhd, Malaysia Cocoa Board and Department of Agriculture Malaysia. She managed to secure around RM6.6 million of cumulative research funding, of which RM1.4 million as the principal investigator. Currently, she oversees 7 Ph.D., 1 MSc, and 2 BSc students as a Main Supervisor. Dr. Maizom assumed the role as referees for articles in peer-reviewed journals such as GM Crops & Food-Biotechnology in Agriculture and the Food Chain, Journal of Oil Palm Research, Sains Malaysiana and Journal of Tropical Plant Physiology. She was also appointed as expert panel/evaluator for Research Foundation Flanders (FWO) Post-Doctoral Fellowship under the European Science Foundation (ESF).

  • Expressions of interest in joining the research collaboration and activity with Associate. Prof. Dr. Maizom’s lab are always welcome. Please contact her via e-mail ( for further discussion.
