Protein Search Results

PatScan searches the Swiss-Prot database.

Results should look something like:

	all
	any(TS) 1...1 GP 1...1 G 4...4 any(LFIVM) G
	sp|P02461|CA13_HUMAN:[1120,1131]:  S P GP A G QQGA I G
	sp|P02461|CA13_HUMAN:[1132,1143]:  S P GP A G PRGP V G
	.
	.
	.
	sp|P42382|CH60_EHRCH:[29,40]    :  T A GP K G LTVA I G
	sp|Q01149|CA21_MOUSE:[749,760]  :  T K GP K G ENGI V G
	COMPLETED REQUEST

The first line indicates that PatScan searched the entire database, and the second line returns the pattern you input. Subsequent lines list the matches to this pattern found in the database. For example:

	sp|P02461|CA13_HUMAN:[1120,1131]:  S P GP A G QQGA I G

can be broken up into 5 fields.

	sp  |  P02461  |  CA13_HUMAN  :  [1120,1131]  :  S P GP A G QQGA I G
        |         |           |               |                   |
        |         |           |               |                   |

    searched      |
              Swiss-Prot
	    Accession number

The output is in alphabetical order based on the first character of the first pattern unit (in this case S first, then T). The matched sequence is broken into 8 segments to match the 8 pattern units of the input pattern. In the above example this breaks up as:

	any(TS) 1...1 GP 1...1 G 4...4 any(LFIVM) G
             |    |   |    |   |   |         |    |
             S    P   GP   A   G  QQGA       I    G

You can access the Swiss-Prot database to get complete information about the protein sequence in which the matched sequence occurs, using:

Accession number (try P02461) or
Swiss-Prot ID (try CA13_HUMAN) or
Either Swiss-Prot Accession number OR Swiss-Prot ID (OR EMBL Accession number).

Nucleotide Search results

PatScan searches the EMBL Nucleotide Sequence Database maintained by EBI.

Results should look something like:

	fungi
	p1=2...2 3...4  p2=4...5  3...3 ~p2 2...3 ~p1
	embl|A02534:[1009,1028]  :  aa acc  cagc  agg gctg  gg  tt
	embl|A06260:[1501,1521]  :  aa ata  taag  gaa ctta  tga tt
	.
	.
	.
	embl|Z50840:[2998,3019]  :  tt agct ctct  aga agag  tgt aa
	embl|Z67741:[458,478]    :  tt gcg  gcgc  ctt gcgc  cag aa
	COMPLETED REQUEST

The first line indicates that PatScan searched the fungi database, and the second line returns the pattern you input. Subsequent lines list the matches to this pattern found in the database. For example:

        embl|A02534:[1009,1028]  :  aa acc  cagc  agg gctg  gg  tt

can be broken up into 4 fields.

	embl  |  A02534  :  [1009,1028]      :  aa acc  cagc  agg gctg  gg  tt
         |          |            |                         |

The output is in alphabetical order based on the first character of the first pattern unit (in this case AA first, with TT last). The matched sequence is broken into 8 segments to match the 8 pattern units of the input pattern. In the above example this breaks up as:

        p1=2...2 3...4  p2=4...5  3...3 ~p2 2...3 ~p1
             |     |         |      |    |    |    |
	     aa   acc       cagc   agg  gctg  gg   tt

You can access the EMBL database to get complete information about the nucleotide sequence in which the matched sequence occurs, using:

Accession number (try A02534).
