My own feeling is that it's biology which wove the web; we're just

we need a coordinated, controlled and defined way of expressing our
mutual confusion. I'd love to have a clear definition of gene (or
protein). In it's absence, a good way of expressing "err..." is
probably
the best we can do.
I don't know whether the BioPAX Level 2 definition of protein is the
most useful one, but at least it sounds clear to me:
protein = anything containing exactly one polypeptide chain
Clear enough?
So insulin is not a protein, wheras a dipeptide is?
Besides which, the issue being discussed here is one of equality. When
are two proteins the same protein?
TWO proteins are never the same protein. Two mangelwurzels are never
the same mangelwurzel, either. What 'same' means, is that there is ONE
thing with two names. Being the same as is never a relationship
between two different things.
