Tricking algae's biological clock boosts production of drugs, biofuels
Date:11/7/2013

ed that the clock consisted of three proteins: KaiA, KaiB and KaiC. Detailed knowledge of the clock's structure allowed them to determine how to switch the clock on and off.

In the current study, the researchers discovered that two components of the clock, KaiA and KaiC, act as switches that turn the cell's daytime and nighttime genes on and off. They have dubbed this "yin-yang" regulation. When KaiA is upregulated produced in larger amounts and KaiC is downregulated produced in smaller amounts then the 95 percent of cell's genes that are active during daylight are turned on, and the 5 percent of the cell's genes that operate during the night are turned off. However, when KaiC is upregulated and KaiA is downregulated then the day genes are turned off and the night genes are turned on.

"As a result, all we have to do to lock the biological clock into its daylight configuration is to genetically upregulate the expression of KaiA, which is a simple manipulation in the genetically malleable cyanobacteria," Johnson said.

To see what effects this capability has on the bacteria's ability to produce commercially important compounds, the researchers inserted a gene for human insulin in some of the cyanobacteria cells, a gene for a fluorescent protein (luciferase) in other cells and a gene for hydrogenase, an enzyme that produces hydrogen gas, in yet others. They found that the cells with the locked clocks produced 200 percent more hydrogenase, 500 percent more insulin and 700 percent more luciferase when grown in constant light than they did when the genes were inserted in cells with normally functioning clocks.
