UBIAD1 (UbiA prenyltransferase domain-containing protein 1) in the endoplasmic reticulum catalyzes the transfer of a geranylgeranyl group from GGPP (geranylgeranyl pyrophosphate)to menadione to form MK4 (vitamin K hydroquinone, menatetrenone) (Nakagawa et al. 2010; Hirota et al. 2013, 2015; Schumacher et al. 2015).
