Text search

The PDBsum text search allows very simple searches of the text found in the PDB header records, which include the TITLE, HEADER, COMPND and SOURCE. the search is ideally suited for single words, such as

    Search string

simple strings (which have to be matched exactly), as in

    Search string
or pairs of words/strings separated by plus signs, " + ",

    Search string

 

Note that some search-words might be present in other words. For example, the simple search for "crystallin" might throw up entries containing the word "crystalline":

1ksz - Entrapment of 6-thiophosphoryl-imp in the active site of crystalline adenylosuccinate synthetase from escherichia coli, data collected at 298k
    TITLE : CRYSTALLINE ADENYLOSUCCINATE SYNTHETASE FROM ESCHERICHIA

To get round this, you can enclose the word, together with a space in front of it and one behind, within double-quotes:

    Search string

Another example might be crystallin from rat. Merely entering:

    Search string

will find not only all crystallin structures which contain the word "rat", but also those containing the word "temperature"

1gcs - Gamma-b crystallin (previously called gamma-ii crystallin) low temperature (150 k) structure
    COMPND: GAMMA-B CRYSTALLIN (PREVIOUSLY CALLED GAMMA-II CRYSTALLIN)
    COMPND: LOW TEMPERATURE (150 K) STRUCTURE

Again, the way around this is to make sure "rat" is treated as a single word by surrounding it by spaces and quotes:

    Search string

which gives:

1a5d - Gammae crystallin from rat lens
    TITLE : GAMMAE CRYSTALLIN FROM RAT LENS
