Methionylthreonylthreonylglutaminylarginyl...isoleucine
A shortened version of the longest english word. The actual word has about 900,000 characters (189,819 to be specific). It is the chemical name for titin, which is the largest known protein. The word is obviously rarely used as it takes about 3 hours to pronounce, and it would be a lot quicker to just say "titin".
If you want some big protein, might want to look for something with a lot of Methionylthreonylthreonylglutaminylarginyl...isoleucine
