secondary to tertiary

[First M. Lastname]

Dear Modelers,

We have a protein for which the crystal structure has not been
determined. Another protein from a family of which our protein is a
member has had its crystal structure determined.

Does anyone know of a program that I could use to make a prediction of
the tertiary structure of our protein based on the comparison of the
secondary structures of the two proteins mentioned above?

Thanks in advance,
