J. Shearer et al., Modeling the reactivity of superoxide reducing metalloenzymes with a nitrogen and sulfur coordinated iron complex, INORG CHEM, 40(22), 2001, pp. 5483
The synthesis and structure of a five-coordinate Fe(II) complex, [(FeSN4)-S
-II-N-Me2 (tren)](PF6) (1), which models the reactive properties of superox
ide reductases (SORs), is reported. SORs catalyze the reduction of superoxi
de to peroxide in anaerobic organisms, thereby avoiding the O-2 formed in t
he more typical superoxide degradation enzyme superoxide dismutase (SOD). T
he thiolate ligand contained in model 1, as well as in SORs appears to play
an important role in promoting SOR activity.
