Since this is not my area of expertise, I searched Google under the key words "protein 'amino acids' nucleotides" to get these possible sources:

These are only a few of the sites available. In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.
I hope this helps. Thanks for asking.
If a protein had 500 amino acids, how many nucleotides would there be?

Well my young dumb american friend, this answer is very obvious. First of - if a protein HAD 500 amino acids, by now that protein is long gone probably expired or the organism has died. Since the protein is dead (according to my calculations - that fact that you posted this on Jan. 2, 2008 means that there is a 99.9999999999999999999999999999999999999999651% that there is no nucleotides needed
