What is a PROT file?

A PROT file is an atom list created and used by XEASY, a Nuclear Magnetic Resonance (NMR) spectrum analysis application. It is a plain text file that describes an atom's nuclear magnetic resonance. PROT files are meant to be opened and viewed in XEASY, using the Load atoms option.

More Information

Scientists and researchers can use XEASY to perform a 3D spectrum analysis of macromolecules, using NMR. One of the measurements XEASY records is a macromolecule's atom list. The atom list contains the name and frequencies of a macromolecule's resonances, and it is saved as a PROT file.

Each PROT file contains several rows of numerical and text values. Each row corresponds to an individual atom, and contains identifying information about that atom. In order, each atom's row includes:

  • The atom's unique ID number
  • The atom's mean chemical shift in part per million
  • The deviation of the atom's assigned peaks from the mean value
  • The atom's name
  • The atom's fragment number
  • The atom's reference lineshapes

To create an atom list in XEASY, scientists use the program's Write atoms (chem.shift) [wc] command. This produces a PROT file for the current macromolecule.

How to open a PROT file

You can open a PROT file in XEASY (Linux), using the program's Load atoms (chem.shift) [lc] command.

If you do not have access to XEASY, you can also open a PROT file in any text editor, to view the atom list it contains.

A PROT file may also be a data file created by GSL Biotech SnapGene, a molecular biology analysis application. It contains a protein sequence and its properties, such as molecular weight and absorbance. PROT files include metadata, such as the creator, a description of the sequence, a history of changes, and comments.

PROT file open in GSL Biotech SnapGene 6

SnapGene is a molecular biology application that documents, designs, and simulates various types of sequences, including DNA, RNA, and protein. When you save a sequence with SnapGene, the software creates a file to store the contents. Snap Gene saves each type of sequence in a different file format:

  • DNA sequence - .DNA file
  • RNA sequence - .RNA file
  • Protein sequence - PROT file

To create a PROT file with SnapGene, follow these steps:

  1. Select File → New Protein File...
  2. Choose the "RNA" sequence type
  3. Create the sequence
  4. Name the file
  5. Select OK

After creating the PROT file, you can save it by selecting File → Save or Save As.... Then, after saving the file, you can close it and re-open it to modify the sequence further.

How to open a PROT file

You can open a PROT file with GSL Biotech SnapGene (multiplatform). To open a PROT file with SnapGene, select File → Open Files....

You can also open a PROT file with SnapGene Viewer (multiplatform). However, it does not provide the same advanced capabilities that SnapGene offers.

How to convert a PROT file

GSL Biotech SnapGene can convert PROT files to various file types, including the following formats:

  • .SEQ - DNA Sequence Text File
  • .FA - FASTA Sequence File
  • .EMBL - EMBL Sequence Data File
  • .GBK - GenBank Data File
  • .TXT - Plain Text File
  • .JPG - JPEG Image
  • .PNG - Portable Network Graphic
  • .EMF - Enhanced Windows Metafile
  • .SVG - Scalable Vector Graphics File
  • .PDF - Portable Document Format
