FunctionPYP_HALHA Photoactive blue light protein. Probably functions as a photoreceptor for a negative phototaxis response. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedPAS (PER-ARNT-SIM) domains are a family of sensor protein domains involved in signal transduction in a wide range of organisms. Recent structural studies have revealed that these domains contain a structurally conserved alpha/beta-fold, whereas almost no conservation is observed at the amino acid sequence level. The photoactive yellow protein, a bacterial light sensor, has been proposed as the PAS structural prototype yet contains an N-terminal helix-turn-helix motif not found in other PAS domains. Here we describe the atomic resolution structure of a photoactive yellow protein deletion mutant lacking this motif, revealing that the PAS domain is indeed able to fold independently and is not affected by the removal of these residues. Computer simulations of currently known PAS domain structures reveal that these domains are not only structurally conserved but are also similar in their conformational flexibilities. The observed motions point to a possible common mechanism for communicating ligand binding/activation to downstream transducer proteins. PAS domains.
