    ..In addition to the single copy of the authentic SOD gene, the genome of H. cutirubrum contains a sequence that is very closely related to but does not code for the previously purified SOD of this organism...

    ..Optimum activity occurs in 2 M KCl; KCl gives about twice as much activity as NaCl over the range of 2 to 4 M. The enzyme appears to be related to those isolated from other archaebacteria but also exhibits several novel features. ..

    ..Production of paraquat resistant mutants of H. cutirubrum may play a part in this process, however, some type of physiological adaptation is also probably required. ..
