GENtle/Protein

In this module, amino acid sequences (peptides/proteins) can be viewed, edited and annotated. It uses a sequence map as main display, and a multi-purpose overview display at the top.

The protein module.

Toolbar

Several functions and display options can be invoked in the tool bar:

• Enter sequence
• Open sequence
• Save sequence
• Print sequence
• Undo
• Cut
• Copy
• Paste
• Plot (shows a plot within the sequence map)
• Horizontal mode

Function display

The smaller display on the top can show several types of information:

Data	Shows some basic data that has been calculated from the sequence
Description	Shows the sequence description
Scheme	Shows a DNA map-like layout of the whole protein
AA weight	Shows a plot of the molecular weight of the individual amino acids
AA isoelectric point	Shows a plot of the isoelectric point of the individual amino acids
Hydrophobicity	Shows a plot of the local hydrophobicity of the amino acids nearby
Chou-Fasman plot	Shows a detailed Chou-Fasman-plot

Special menus

Edit/Photometer analysis	Invokes the respective calculator
Edit/'Backtranslate' DNA	Attempts to generate the DNA sequence which codes for this amino acid sequence, using the full range of IUPAC base letters
Edit/Proteolysis assistant	Invokes the proteolysis assistant
