Intein Name: Tli pol-1. The intein name should consist of a 3 letter organism specification, where the first letter is the first letter of the Genus (Thermococcus) and the second and third letters are a Species designation (litoralis). The organism abbreviation is then followed by an abbreviation for the extein gene (Pol). If more than 1 intein is present in a gene, they should be numbered in order of appearance from the N- to C-terminus. For organisms with only a genus designation and an isolate code, such as Psp Pol or Tsp Pol inteins, include a strain designation - Example: Psp-KOD Pol.

Intein size (aa): List the number of amino acids in the intein, not including the C-extein S/T/C.

Endo Activity: If endonuclease activity has been demonstrated, list endonuclease name. Convention dictates that the endonuclease name is preceded by the 'PI-' prefix.

Endo Motif: List: 'DOD' if a member of the LAGLIDADG or dodecapeptide motif family; 'HNH' if a member of the HNH family; 'none' if no large insert is present between intein Blocks B and F; and 'unknown' if a large insert (>100 aa) is present that doesn't have any of the known homing endonuclease signature motifs. Leave blank if you are not sure.

Location in extein (aa preceding intein): List the amino acid preceding the intein (using the single letter code) and its position in the extein, with amino acid 1 being the initiating Met of the extein gene.

N-terminal Splice Junction: Last 10 N-extein residues/intein N-terminus (single letter code).

C-terminal Splice Junction: Last 2 amino acids of the intein/first 10 amino acids of the C-extein (single letter code).

Insert Site: Include the insertion site name consisting of the abbreviated extein name and an alphabetic designation for insertion sites in that extein, taking into account the previously identified insertion sites in extein homologs. Also list notable landmarks like motifs or active site residues.
