There is a nice paper Comput Biol Chem. 2009 Dec;33(6):445-50. Epub 2009 Oct 20. Predicting melting temperature directly from protein sequences.
Ku T, Lu P, Chan C, Wang T, Lai S, Lyu P, Hsiao N. They have a list of 35 different proteins with their Tms with the references from where they obtained their data. Hope this aids in your work. Dan
