I hark back to Mark Purdey's research on patients with copper depletion and exposure to trivalent manganese. The copper deficient proteins can bind manganese in place of the copper. The trivalent manganese is then capable for forming the "tendrils" typical of the defective proteins.

Interesting analogy here.

Thanks for the mention of Purdey. Bookmarked for later.
