PAS domains. Common structure and common flexibility.
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 ...
متن کاملNewly Identified Motifs within PAS Domains of Filamentous Cyanobacteria
Many cyanobacterial genome projects have been finished or are ongoing. Now, complete genome sequence of Anabaena sp. PCC 7120 (Anabaena)[1] and draft genome sequence of Nostoc punctiforme (Nostoc)[3] are available. Phylogenetically, these species are closely related. These species have extremely abundant signal-transduction proteins, especially PAS domain-containing proteins (PAScontaining prot...
متن کاملPAS domains: internal sensors of oxygen, redox potential, and light.
PAS domains are newly recognized signaling domains that are widely distributed in proteins from members of the Archaea and Bacteria and from fungi, plants, insects, and vertebrates. They function as input modules in proteins that sense oxygen, redox potential, light, and some other stimuli. Specificity in sensing arises, in part, from different cofactors that may be associated with the PAS fold...
متن کاملReduction in Cache Memory Power Consumption based on Replacement Quantity
Today power consumption is considered to be one of the important issues. Therefore, its reduction plays a considerable role in developing systems. Previous studies have shown that approximately 50% of total power consumption is used in cache memories. There is a direct relationship between power consumption and replacement quantity made in cache. The less the number of replacements is, the less...
متن کاملStructural Properties of PAS Domains from the KCNH Potassium Channels
KCNH channels form an important family of voltage gated potassium channels. These channels include a N-terminal Per-Arnt-Sim (PAS) domain with unknown function. In other proteins PAS domains are implicated in cellular responses to environmental queues through small molecule binding or involvement in signaling cascades. To better understand their role we characterized the structural properties o...
