Putting "sulfotyrosine molecular dynamics" into Google Scholar I find the
following paper:
Glover and Tracey, Structure, modelling, and molecular dynamics studies of
the inhibition of protein tyrosine phosphatase 1B by sulfotyrosine
peptides, *Biochemistry and Cell Biology*, *1999*, *77*, 469-486.
The literature it almost always a better place to start for such things
than the AMBER listserv.

P.S. Sulfur in AMBER is probably best handled by GAFF, for which atom types
are either automatically assigned by Antechamber and/or easily confirmed by
looking at the parameter definitions. These are not always satisfying (for
example P-S bonds) and the Lennard-Jones parameters are probably not fully
optimized (they are the same in all cases).
