Function

Search for patterns in protein sequences (translated)

Description

fuzztran searches for a specified PROSITE-style pattern in nucleic acid sequences that are first translated to protein in the specified frame(s) with a specified genetic code. Such patterns are specifications of a (typically short) length of sequence to be found. They can specify a search for an exact sequence or they can allow various ambiguities, matches to variable lengths of sequence and repeated subsections of the sequence. One or more nucleotide sequences are read from file. The output is a standard EMBOSS report file that includes data such as location and score of any matches.

Search for patterns in protein sequences (translated)
Version: EMBOSS:6.5.0.0

   Standard (Mandatory) qualifiers:
  [-sequence]          seqall     Nucleotide sequence(s) filename and optional
                                  format, or reference (input USA)
   -pattern            pattern    The standard IUPAC one-letter codes for the
                                  amino acids are used.
                                  The symbol 'x' is used for a position where
                                  any amino acid is accepted.
                                  Ambiguities are indicated by listing the
                                  acceptable amino acids for a given position,
                                  between square parentheses '[ ]'. For
                                  example: [ALT] stands for Ala or Leu or Thr.
                                  Ambiguities are also indicated by listing
                                  between a pair of curly brackets '{ }' the
                                  amino acids that are not accepted at a gven
                                  position. For example: {AM} stands for any
                                  amino acid except Ala and Met.
                                  Each element in a pattern is separated from
                                  its neighbor by a '-'. (Optional in
                                  fuzztran)
                                  Repetition of an element of the pattern can
                                  be indicated by following that element with
                                  a numerical value or a numerical range
                                  between parenthesis. Examples: x(3)
                                  corresponds to x-x-x, x(2,4) corresponds to
                                  x-x or x-x-x or x-x-x-x.
                                  When a pattern is restricted to either the
                                  N- or C-terminal of a sequence, that pattern
                                  either starts with a '<' symbol or
                                  respectively ends with a '>' symbol.
                                  A period ends the pattern. (Optional in
                                  fuzztran).

Input file format

fuzztran reads in one or more nucleotide sequences.

The input is a standard EMBOSS sequence query (also known as a 'USA').

Major sequence database sources defined as standard in EMBOSS installations include srs:embl, srs:uniprot and ensembl

Data can also be read from sequence output in any supported format written by an EMBOSS or third-party application.

The input format can be specified by using the command-line qualifier -sformat xxx, where 'xxx' is replaced by the name of the required format. The available format names are: gff (gff3), gff2, embl (em), genbank (gb, refseq), ddbj, refseqp, pir (nbrf), swissprot (swiss, sw), dasgff and debug.

See: http://emboss.sf.net/docs/themes/SequenceFormats.html for further information on sequence formats.

Pattern specification

Patterns for fuzztran are based on the format of pattern used in the PROSITE database, with the difference that the terminating dot '.' and the hyphens, '-', between the characters are optional.

The PROSITE pattern definition from the PROSITE documentation follows.

For example, you can look for the pattern:


[DE](2)HS{P}X(2)PX(2,4)C

This means: Two Asps or Glus in any order followed by His, Ser, any residue other then Pro, then two of any residue followed by Pro followed by two to four of any residue followed by Cys.

The search is case-independent, so 'AAA' matches 'aaa'.

Output file format

The output is a standard EMBOSS report file.

The results can be output in one of several styles by using the command-line qualifier -rformat xxx, where 'xxx' is replaced by the name of the required format. The available format names are: embl, genbank, gff, pir, swiss, dasgff, debug, listfile, dbmotif, diffseq, draw, restrict, excel, feattable, motif, nametable, regions, seqtable, simple, srs, table, tagseq.

See: http://emboss.sf.net/docs/themes/ReportFormats.html for further information on report formats.

By default fuzztran writes a 'table' report file.

The columns of data are as follows:

  1. Start - the start position of the pattern in the nucleic acids sequence.
  2. End - the end position of the pattern in the nucleic acids sequence.
  3. Score - the score of the match.
  4. Mismatch - the number of mismatches .
  5. Frame - the translation frame that the pattern match occurs in.
  6. PStart - the start position of the match in the resulting protein sequence.
  7. PEnd - the end position of the match in the resulting protein sequence.
  8. Translation - the protein sequence that is matched.

Data files

EMBOSS data files are distributed with the application and stored in the standard EMBOSS data directory, which is defined by the EMBOSS environment variable EMBOSS_DATA.

To see the available EMBOSS data files, run:

% embossdata -showall

To fetch one of the data files (for example 'Exxx.dat') into your current directory for you to inspect or modify, run:


% embossdata -fetch -file Exxx.dat

Users can provide their own data files in their own directories. Project specific files can be put in the current directory, or for tidier directory listings in a subdirectory called ".embossdata". Files for all EMBOSS runs can be put in the user's home directory, or again in a subdirectory called ".embossdata".

The directories are searched in the following order:

The Genetic Code data files are based on the NCBI genetic code tables. Their names and descriptions are:

EGC.0
Standard (Differs from GC.1 in that it only has initiation site 'AUG')
EGC.1
Standard
EGC.2
Vertebrate Mitochodrial
EGC.3
Yeast Mitochondrial
EGC.4
Mold, Protozoan, Coelenterate Mitochondrial and Mycoplasma/Spiroplasma
EGC.5
Invertebrate Mitochondrial
EGC.6
Ciliate Macronuclear and Dasycladacean
EGC.9
Echinoderm Mitochondrial
EGC.10
Euplotid Nuclear
EGC.11
Bacterial
EGC.12
Alternative Yeast Nuclear
EGC.13
Ascidian Mitochondrial
EGC.14
Flatworm Mitochondrial
EGC.15
Blepharisma Macronuclear
EGC.16
Chlorophycean Mitochondrial
EGC.21
Trematode Mitochondrial
EGC.22
Scenedesmus obliquus
EGC.23
Thraustochytrium Mitochondrial

The format of these files is very simple.

It consists of several lines of optional comments, each starting with a '#' character.

These are followed the line: 'Genetic Code [n]', where 'n' is the number of the genetic code file.

This is followed by the description of the code and then by four lines giving the IUPAC one-letter code of the translated amino acid, the start codons (indicdated by an 'M') and the three bases of the codon, lined up one on top of the other.

For example:

   
------------------------------------------------------------------------------
# Genetic Code Table

# Obtained from: http://www.ncbi.nlm.nih.gov/collab/FT/genetic_codes.html
# and: http://www3.ncbi.nlm.nih.gov/htbin-post/Taxonomy/wprintgc?mode=c
#
# Differs from Genetic Code [1] only in that the initiation sites have been
# changed to only 'AUG'
