 From a practical point of view, it is conceivable that some people would 
want to make statements about a web page or another specific representation 
of this "database entry", so we need a different URI for each:

http://purl.uniprot.org/uniprot/P00750 <- "database entry"
http://beta.uniprot.org/uniprot/P00750 <- an HTML representation
http://beta.uniprot.org/uniprot/P00750.rdf <- an RDF representation
http://beta.uniprot.org/uniprot/P00750.fasta <- a FASTA representation

Now we could have a lot of fun arguing over what exactly this "database 
entry" is, whether or not it corresponds to someone's concept of "protein", 
and more generally, what any of this is meant to reflect in the "real" 
world. But I don't see any point in such a discussion -- not unless someone 
can demonstrate that there are practical implications for any of this.
