* Flavodoxin signature *
************************

Flavodoxins [1]  are  electron-transfer  proteins  that  function  in  various
electron transport systems. Flavodoxins bind one FMN molecule, which serves as
a redox-active prosthetic group.  Flavodoxins are functionally interchangeable
with ferredoxins. They have been isolated from prokaryotes, cyanobacteria, and
some eukaryotic algae.     The signature pattern for these proteins is derived
from a conserved  region in  their N-terminal section, this region is involved
in the binding of the FMN phosphate group.
