  • Title: The reaction of hydroxyurea with oxyhaemocyanin and methaemocyanin of the crayfish Astacus leptodactylus and the snail Helix pomatia.
    Author: Van Hoof D, Witters R, Lontie R.
    Journal: Biochem J; 1988 Sep 01; 254(2):605-7. PubMed ID: 3178776.
    Abstract:
    The reaction of hydroxyurea with the oxyhaemocyanins of Astacus leptodactylus and Helix pomatia yielded methaemocyanins which could be regenerated with hydroxylamine. Hydroxyurea did not react with Astacus methaemocyanin, but quantitatively regenerated Helix methaemocyanin under N2. The reaction of hydroxyurea with Helix haemocyanin at pH 5.7 under air thus led to a steady state, with an oxyhaemocyanin/methaemocyanin ratio of 2.05:1.
