How reliable is Alphafold2 for folding random-coil peptide

I have a peptide X of length 50aa. Alphafold2 predicted the structure which takes a helix form and with high average pLDDT score (>90). But during actual experiment (e.g. crystallography, ...

Does DeepMind's new protein folding software (AlphaFold) also work well for metalloproteins (proteins with metal cofactors)?

(1) Commonly, the metal is at the active site which needs the most prediction precision. (2) Typically, there is only one (or a few) metals in a protein, which contains far more other atoms. So, the ...
