hexs-a

Gene
hexs-a
Protein
Hexaprenyl-diphosphate synthase small subunit ((2E,6E)-farnesyl-diphosphate specific)
Organism
Micrococcus luteus
Length
143 amino acids
Function
Catalyzes the condensation of three molecules of isopentenyl diphosphate with farnesyl diphosphate (FPP) to yield (all-E)-hexaprenyl diphosphate (HexPP; C30), the precursor of the prenyl side chain of menaquinone-6. Large subunit Hexs-B catalyzes the condensation reaction and the final product chain length is cooperatively regulated by both the Hexs-A and Hexs-B subunits using the whole size of the hydrophobic cleft as a ruler.
