24.4.4. BMCD implementation – web interface

| top | pdf |

The BMCD is a web-accessible resource available to the crystallographic community through the website at http://wwwbmcd.nist.gov:8080/bmcd/bmcd.html . The current version of the BMCD includes 3547 crystal entries from 2526 biological macromolecules. The web interface provides an easy mechanism for browsing through the data contained in the BMCD. The user can examine the complete list of macromolecule names and tabulations of the number of macromolecules and crystal forms for each source, prosthetic group, space group, chemical addition and crystallization method. In addition, the listing of complete references is available along with a set of general references concerning all aspects of crystal growth.

The web interface offers a number of ways to query the database. For example, the results of precomputed queries are available through the tabulations of chemical additives, space groups, crystallization methods and prosthetic groups mentioned above. The tables provide links to lists of macromolecules and crystal forms that match the database query for these parameters. Allowing the user to enter specific parameter values that must be matched provides another method of searching the database. Examples of this include querying for macromolecules based on their molecular weight. A user may also search for crystal forms of macromolecules that crystallize at a particular temperature, macromolecule concentration and pH. A range of values or a single value of one or all of the parameters may be used to limit the search. For references, queries for specific authors, keywords and journal information are allowed.
