SEARCH TEXT acids

On TOXLINE, field names are identified by a two-letter mnemonic. A list of ETIC fields and their field identifiers on TOXLINE appears in Table 10. If the two-letter identifier is not used in searching, retrieval defaults to free-text searching of an index created by single words from all searchable fields. Thus, if one does not use identifiers, a search for acetylsalicylic acid must be worded ETIC AND ACETYLSALICYLIC AND ACID. Individual words in only the TI, KW, and AB fields are searchable via text words (TW). Indexing terms in most of the technical fields have been put into the keyword (KW) field. 

Table IV contains a listing of the substances whose administration has been reported as increasing the urinary glucuronic acid, and of compounds for which some evidence for glucuronic acid conjugation exists, but of which no glucuronic conjugate has actually been isolated. The compounds of Table III and, usually, their metabolic precursors have been omitted. Here, except as noted, specific references to the literature will be found in Williams text.1 Unfortunately, this list is not complete some of the references were found only by careful search, and there are probably many more buried in the literature.

The common atomic coordinate files for 3D structure in biochemistry is PDB format. The pdb files of polysaccharides, proteins, and nucleic acids can be retrieved from the Protein Data Bank at RCSB (http //www.rcsb.org/pdb/). On the home page (Figure 4.15), enter PDB ID (check the box query by PDB id only ) or keywords (check the box match exact word ) and click Find a structure button. Alternatively, initiate search/retrieval by selecting SearchLite. On the query page, enter the keyword (e.g., the name of ligand or biomacromolecule) and click Search button. Select the desired entry from the list of hits to access Summary information of the selected molecule. From the Summary information, select Download/Display file and then PDB Text and PDB noncompression format to retrieve the pdb file. In order to display 3D structure online, choose View structure followed by selecting one of 3D display options. The display can be saved in. jpg or. gif image format. 

The exon-intron database can be downloaded from EID at http //www.mcb.-harvard.edu/gilbert/EID/, whereas online database search can be conducted at Exlnt (http //intron.bic.mus.edu.sg/exint/exint.html). On the Exlnt home page, click Search Exlnt by keywords to open the query page. Choose Complete Exlnt for the Database, choose Text word for Search field, and enter the keyword (protein name, e.g., hexokinase, lysozyme). Click the Submit button to receive search results. The output includes locus name, description (viz. GenBank), NCBI ID and pointer (nucleotide sequence), phase and position of introns, number, size, and length (in amino acids) of exons, nucleotide position for the introns, and protein sequence...
