Genetic Basis of Variable Expression of Glycan Xeno-Autoantigens by Cattle. Meat and dairy products from cattle contain sugar structures (glycans) that are not made by humans. These structures can be recognised by the immune system and lead to allergic reactions, inflammation and potentially cancer. These non-human structures are called xeno-autoantigens or XAs. We have discovered individual cattle that do not produce one of these XAs. We will study the gene required to make XA in the XA-free ca ....Genetic Basis of Variable Expression of Glycan Xeno-Autoantigens by Cattle. Meat and dairy products from cattle contain sugar structures (glycans) that are not made by humans. These structures can be recognised by the immune system and lead to allergic reactions, inflammation and potentially cancer. These non-human structures are called xeno-autoantigens or XAs. We have discovered individual cattle that do not produce one of these XAs. We will study the gene required to make XA in the XA-free cattle to find the underlying mutation. The same approach will be used to look for natural XA-free individuals in other food species. This knowledge may enable us to create a test to facilitate the natural breeding of non-GMO, XA-free livestock to benefit Australian primary producers and provide safer food for consumers.Read moreRead less
Evolving enzymes to harness the clean energy reserves of nature. We want to improve enzymes that are used by nature to harness huge amounts of energy - the energy present in glucose, one of the most abundant materials in the biosphere. The enzymes will be evolved to efficiently produce biological power in a practically useable form rather than for the growth of the organisms from which they originated. We will use this energy to drive the synthesis of chemicals of practical value, truly green ch ....Evolving enzymes to harness the clean energy reserves of nature. We want to improve enzymes that are used by nature to harness huge amounts of energy - the energy present in glucose, one of the most abundant materials in the biosphere. The enzymes will be evolved to efficiently produce biological power in a practically useable form rather than for the growth of the organisms from which they originated. We will use this energy to drive the synthesis of chemicals of practical value, truly green chemistry. We also seek to answer questions such as: how do proteins evolve, how do enzymes work and how can biochemical pathways be optimised for industrial processes? This information will be of fundamental benefit for the use of enzymes in green chemistry, providing cleaner ways to produce important chemicals. Read moreRead less
