# pepwheel(1e)

Draw a helical wheel diagram for a protein sequence

## NAME

pepwheel - Draw a helical wheel diagram for a protein sequence

## SYNOPSIS

**pepwheel** **-sequence** *sequence* **-wheel** *boolean* \[**-steps** *integer*\] \[**-turns** *integer*\] **-graph** *graph* **-amphipathic** *toggle* **-squares** *string* **-diamonds** *string* **-octags** *string*

**pepwheel** **-help**

## DESCRIPTION

**pepwheel** is a command line program from EMBOSS (“the European Molecular Biology Open Software Suite”). It is part of the "Display,Protein:2D Structure" command group(s).

## OPTIONS

### Input section

- **-sequence** *sequence*

  ### Output section

- **-wheel** *boolean*

  Default value: Y

- **-steps** *integer*

  The number of residues plotted per turn is this value divided by the 'turns' value. Default value: 18

- **-turns** *integer*

  The number of residues plotted per turn is the 'steps' value divided by this value. Default value: 5

- **-graph** *graph*

  ### Markup section

- **-amphipathic** *toggle*

  If this is true then the residues ACFGILMVWY are marked as squares and all other residues are unmarked. This overrides any other markup that you may have specified using the qualifiers '-squares', '-diamonds' and '-octags'.

- **-squares** *string*

  By default the aliphatic residues ILVM are marked with squares. Default value: ILVM

- **-diamonds** *string*

  By default the residues DENQST are marked with diamonds. Default value: DENQST

- **-octags** *string*

  By default the positively charged residues HKR are marked with octagons. Default value: HKR
