I have a solution if some additonal information is available.  A comparison of 
this gene to known eukaryotic and prokaryotic counterparts seems worthwhile.  
The sequence, preferably amino acid, is probably most similar to either 
another eukaryotic or prokaryotic sequence depending on its origin.

Hope that the appropriate data are available.
