The names in your db file, have to match those in the Amber libraries. For
the hydrogen mis-matches, you can just remove those atoms from the pdb, and
let LEaP put them in. For phosphotyrosine, you have to change the residue
name to match a residue you would read in (check the contributed parameters
database at the Amber web site). Amber thinks that TYR is ordinary tyrosine.

...good luck...dac
