Structures at atomic resolution (up to 1.0 A) which contain bases, sugars or the phosphodiester linkage, were selected from the Nucleic Acid Database or the Cambridge Structural Database to build a nucleic acid dictionary from X-ray refined structures. The dictionary consists of the average values for bond distances, bond angles and dihedral angles. The(More)
The classification feast/famine regulatory proteins (FFRPs) encompasses archaeal DNA-binding proteins with Escherichia coli transcription factors, the leucine-responsive regulatory protein and the asparagine synthase C gene product. In this paper, we describe two forms of the archaeal FFRP FL11 (pot0434017), both assembled from dimers. When crystallized, a(More)
Feast/famine regulatory proteins comprise a diverse family of transcription factors, which have been referred to in various individual identifications, including Escherichia coli leucine-responsive regulatory protein and asparagine synthase C gene product. A full length feast/famine regulatory protein consists of the N-terminal DNA-binding domain and the(More)
The crystal structure of TATA binding protein (TBP) from a mesothermophilic archaeon, Sulfolobus acidocaldarius, has been determined at a resolution of 2.0 A with an R factor of 20.9%. By comparing this structure with the structures of TBPs from a hyperthermophilic archaeon and mesophilic eukaryotes, as well as by comparing amino acid sequences of TBPs from(More)
The neural basis of memory subprocesses, encoding and retrieval, have been extensively examined in functional neuroimaging studies. However, the cortical substrates of taste memory, which form an important part of our episodic memory, have rarely been explored in humans. Previously, we have used functional near-infrared spectroscopy (fNIRS) and found(More)
OBJECTIVE The use of functional near-infrared spectroscopy (fNIRS) is growing, leading to a need for methods to summarise data from multiple studies. However, this is difficult using the current channel-based methods when experiments do not share a common channel (CH) arrangement. Thus, we proposed and implemented a CH-independent analysis method for(More)
The Nucleic Acid Database is a relational database containing information about three-dimensional nucleic acid structures. The methods used for data processing, structure validation, database management and information retrieval, as well as the various services available via the World Wide Web, are described. Plans for the future include greater reliance on(More)
The act of tasting is the product of inseparable integrative behavior consisting of multi-sensory processing and orolingual motor coordination. Often tasting-induced brain activity is looked at in a reductionist manner as a set of isolated components. However, brain activity as a whole during tasting may not simply be the sum of isolated brain responses;(More)
We examined whether food identity information presented as name labels would influence perception of basic tastes. To test this hypothesis, we used 10 aqueous taste solutions consisting of 2-3 of the 5 basic tastes in different ratios and presented them with one of these food names: "lemon," "coffee jelly," "caramel candy," and "consomme soup." Forty-six(More)
BACKGROUND Health numeracy is an important factor in how well people make decisions based on medical risk information. However, in many countries, including Japan, numeracy studies have been limited. METHODS To fill this gap, we evaluated health numeracy levels in a sample of Japanese adults by translating two well-known scales that objectively measure(More)
