- * 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.
-
- -Consensus pattern: [LIV]-[LIVFY]-[FY]-x-[ST]-x(2)-[AG]-x-T-x(3)-A-x(2)-[LIV]
- -Sequences known to belong to this class detected by the pattern: ALL.
- -Other sequence(s) detected in SWISS-PROT: 4.
- -Last update: November 1990 / Pattern and text revised.
