Comparison of the refined crystal structures of wild-type (1.34 Å) flavodoxin from Desulfovibrio vulgaris and the S35C mutant (1.44 Å) at 100 K

The structure at 100 K (synchrotron radiation) of the S35C mutant of D. vulgaris flavodoxin at 1.44 Å resolution has been compared with the refined wild-type (wt) structure at 1.34 Å resolution. A different orientation of the Cys35 thiol group with respect to the Ser35 hydroxyl has been found.
