menJ

Gene
menJ
Protein
Menaquinone reductase
Organism
Mycobacterium smegmatis (strain ATCC 700084 / mc(2)155)
Length
409 amino acids
Function
Catalyzes the reduction of a single double bond in the isoprenoid tail of menaquinone (MK-9) in M.smegmatis, likely the beta-isoprene unit, forming the predominant form of menaquinone found in mycobacteria, MK-9(II-H2).
Similarity
Belongs to the geranylgeranyl reductase family.
