NADH PEROXIDASE WITH CYSTEINE-SULFENIC ACID
OverviewOverview
In order to obtain the crystal structure of the flavoprotein NADH, peroxidase with its native Cys42-sulfenic acid redox center, a strategy, combining reduced exposure of crystals to ambient oxygen and data, collection at -160 degrees C was applied. The structure of the native, enzyme to 2.8 A resolution is described; these results conclusively, establish the existence of the Cys42-sulfenic acid as the functional, non-flavin redox center of the peroxidase and provide the first structure, for any naturally occurring protein-sulfenic acid. The Cys42-sulfenic acid, atoms C alpha-C beta-S gamma-O roughly define a planar arrangement which, is stacked parallel to the si face of the FAD isoalloxazine and positions, the sulfenyl oxygen atom only 3.3 A from FAD-C4A. His10-N epsilon 2, contributes a ... [(full description)]
