Abstract
|
|
|
The structure of the heterodimeric flavocytochrome c sulfide dehydrogenase from
Chromatium vinosum was determined at a resolution of 2.53 angstroms. It contains
a glutathione reductase-like flavin-binding subunit and a diheme cytochrome
subunit. The diheme cytochrome folds as two domains, each resembling
mitochondrial cytochrome c, and has an unusual interpropionic acid linkage
joining the two heme groups in the interior of the subunit. The active site of
the flavoprotein subunit contains a catalytically important disulfide bridge
located above the pyrimidine portion of the flavin ring. A tryptophan,
threonine, or tyrosine side chain may provide a partial conduit for electron
transfer to one of the heme groups located 10 angstroms from the flavin.
