Protein conformation: through a lens, darkly.
This commentary describes the study by Calleja and co-workers, who have used fluorescence resonance energy transfer between two fluorescent proteins fused to one protein kinase (protein kinase B/Akt) to reveal conformational changes in a functional protein. The findings of their study offer an intriguing insight into the behaviour of an enzyme that is essential for multiple aspects of mammalian signalling.
