Anyone know a protein with real low pI ?

I am looking for a protein of pI less than 3, which is NOT pepsin or an 
acidic protease. Other desirable qualities include fairly low molecular 
weight and it should be easily obtainable.

Also, is there a database anywhere of experimentally determined pIs ?

Any assistance appreciated !
