    The genome of the human pathogen Mycobacterium tuberculosis (Mtb) encodes ∼4,400 proteins, but one third of them have unknown functions. We solved the crystal structure of Rv3651, a hypothetical protein with no discernible similarity to proteins with known function. Rv3651 has a three-domain architecture that combines one cGMP-specific phosphodiesterases, adenylyl cyclases and FhlA (GAF) domain and two Per-ARNT-Sim (PAS) domains. GAF and PAS domains are sensor domains that are typically linked to signaling effector molecules. Unlike these sensor-effector proteins, Rv3651 is an unusual sensor domain-only protein with highly divergent sequence. The structure suggests that Rv3651 integrates multiple different signals and serves as a scaffold to facilitate signal transfer.
