Please, stop talking about percent similarity. There is no information in 
percent similarity. If you want to talk about percent similarity, you have
to cite the matrix you use, and noone is able to say what scores are in a
matrix...In a protein, you can easily see that similarity depends of the
position in the sequence. You can not define the same similarity (in terms of
functional analysis) for a reisdue in an helix, a loop, a sheet or in the
active site.
	Well, I'm not in the better place to give such lessons, but noone else
want to do that...
						Bye,
							Francois.
