Towards the end of 2013, researchers at the Pacific Northwest National Laboratory (PNNL) hit the news with an analytical first: the monitoring of redox activity in specific proteins within living cells (1). Redox reactions, which modulate protein function by adding or subtracting electrons, make up a rapid regulatory network that is involved in many aspects of cell function. Increased knowledge of the process is particularly exciting in the field of biofuels, where “tinkering” with key proteins can regulate the production of useful chemicals.We caught up with Aaron Wright, senior scientist in Omics Biological Applications (Biological Sciences Division, PNNL) and team leader of the project.
