Don't use '-missing'. Since you're a beginner you're not allowed to
(unless you get a permit for it from one of the developers).

This is the result of using '-missing'.

Well, as I recall, but I may need to check my biochemistry books here,
there's no S in tyrosine. Is this a modified residue, or is there just
something _else_ wrong with your starting structure? Note that I say
something else, since you clearly also have missing atoms, which you
need to fix. Go work on the starting structure!
