It seems as if places that have information on enzymes and proteins tend to only tell you the ribbon structure and not tell you what atoms they are made up of or how those atoms connect to each other. That is what I am truly interested in studying.

 

In particular I am trying to find information on the molecular structures of Tyrosine Hydroxylase and Aromatic L-amino acid decarboxylase.

 

Any information would be helpful.

If you look for amino acid sequences you might find them and you can work out the atoms from that

though I can't see what use this will be for you.

I am not sure what you want precisely, but experimentally resolved protein structure are typically found e.g. in the RCSB protein data bank.
