Targeting and stabilizing proteins in sugar storage vacuoles for metabolic engineering in sugarcane. We have isolated a novel gene for an enzyme that efficiently converts sucrose into a product of much higher value. We have shown that the enzyme functions in sugarcane, a first example of the potential for new biosynthetic capacities in this highly productive crop. Because 90% of stored sucrose is in specialized vacuoles, the enzyme needs to be directed into these vacuoles, and made stable and ac ....Targeting and stabilizing proteins in sugar storage vacuoles for metabolic engineering in sugarcane. We have isolated a novel gene for an enzyme that efficiently converts sucrose into a product of much higher value. We have shown that the enzyme functions in sugarcane, a first example of the potential for new biosynthetic capacities in this highly productive crop. Because 90% of stored sucrose is in specialized vacuoles, the enzyme needs to be directed into these vacuoles, and made stable and active there. This is feasible by building on recent discoveries about vacuolar targeting in plants. The outputs include scientific understanding to underpin metabolic engineering in plants, and a profitable high-technology export industry for Australia.Read moreRead less
