PHOTOACTIVE YELLOW PROTEIN 1-25 DELETION MUTANT
Overview
PAS (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 ... [(full description)]
