Becky, NCBI switched over to a web service model years ago. Check out their eutils page for more info. If you do a lot of work with their data, I would recommend signing up on their mailing list.

For this particular query I think you would need to make an esearch request and then an efetch (but the folks at NCBI would now better): 

http://eutils.ncbi.nlm.nih.gov/entrez/eutils/search.fcgi?db=protein&te
+rm=148261691&rettype=uilist&usehistory=y

[download]
and then using the info from esearch (basically WebEnv and query_key): 
 
http://eutils.ncbi.nlm.nih.gov/entrez/eutils/efetch.fcgi?db=protein&We
+bEnv=<xxx>&query_key=<yyy>&rettype=fasta&retmode=xml&sort=pub+date

[download]

Update: The NCBI folks may have a better way of *directly* pulling the data based on ids -- I only query pubmed and the app normally has to do a search first so this search/fetch approach always worked well for me.

Update: Well ... it looks like you can directly pull: 

http://eutils.ncbi.nlm.nih.gov/entrez/eutils/efetch.fcgi?db=protein&id
+=148261691&rettype=fasta

Like I said, I really like what the NCBI folks are doing.
