in the light of structure determinations of mt containing zn ( ii ) and/or cd ( ii ) [ w. braun et al . ( 1986 ) j. mol . biol . 187 , 125-129 , and w. f. furrey et al . ( 1986 ) science ( wash. dc ) 231 , 704-710 ] , which revealed two metal-thiolate clusters containing three and four metal ions , respectively , and involving all 20 cysteine residues in metal binding , the appearance of mossbauer parameters characteristic of three isolated fe ( ii ) sites in 57fe ( ii ) 7-mt is peculiar and deserves further studies .
