The Effects Of Noncovalent Interactions Studied By Ultrafast Two-Dimensional Infrared Spectroscopy
… investigated the effects of hydrogen bonding on phylloquinone, a biological cofactor that plays an important role in photosynthetic electron transfer. Previous studies have shown that the local protein environment can tune the redox properties of phylloquinone; however, the exact mechanism and …

Development of novel approaches for industrial fermentation of menaquinone-7
… in the diet. Menaquinones (MK) together with phylloquinone (PK) fall under the common name ‘vitamin K’. Recent studies show that dietary intake of menaquinones results in more health benefits than phylloquinone. Menaquinone-7 (MK-7) plays an important role in maintaining human health in the …

Fermentation of vitamin K2 (menaquinone-7): Development of an optimal fermentation process to selectively enhance the production of the biologically significant all-trans isomer
… related compounds, namely vitamin K1 (phylloquinone), vitamin K2 (menaquinones), and vitamin K3 (menadione), which share a common 2-methyl-1,4-naphthoquinone moiety but differ in the structure of a lateral isoprenoid chain at the 3-position. Despite their structural similarities, all K …

Molekulare Ursachen Vitamin K-abhängiger Gerinnungsstörungen
Vitamin K ist ein essentieller Cofaktor für die posttranslationale Gamma-Carboxylierung von sog. Vitamin K-abhängigen Gerinnungsfaktoren, Knochenproteinen, Zellwachstum-regulierenden und weiteren Proteinen mit noch unbekannter Funktion. Defekte im Vitamin K-Stoffwechsel führen einerseits zu zwei …
