Functional Characterization of the Vitamin K2 Biosynthetic Enzyme UBIAD1
UbiA prenyltransferase domain-containing protein 1 (UBIAD1) plays a significant role in vitamin K2 (MK-4) synthesis. We investigated the enzymological properties of UBIAD1 using microsomal fractions from Sf9 cells expressing UBIAD1 by analysing MK-4 biosynthetic activity. With regard to UBIAD1 enzyme reaction conditions, highest MK-4 synthetic activity was demonstrated under basic conditions at...
متن کاملVitamin K2 Biosynthetic Enzyme, UBIAD1 Is Essential for Embryonic Development of Mice
UbiA prenyltransferase domain containing 1 (UBIAD1) is a novel vitamin K2 biosynthetic enzyme screened and identified from the human genome database. UBIAD1 has recently been shown to catalyse the biosynthesis of Coenzyme Q10 (CoQ10) in zebrafish and human cells. To investigate the function of UBIAD1 in vivo, we attempted to generate mice lacking Ubiad1, a homolog of human UBIAD1, by gene targe...
متن کاملUBIAD1-mediated vitamin K2 synthesis is required for vascular endothelial cell survival and development.
Multi-organ animals, such as vertebrates, require the development of a closed vascular system to ensure the delivery of nutrients to, and the transport of waste from, their organs. As a result, an organized vascular network that is optimal for tissue perfusion is created through not only the generation of new blood vessels but also the remodeling and maintenance of endothelial cells via apoptot...
متن کاملthe effect of functional/notional approach on the proficiency level of efl learners and its evaluation through functional test
in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...
15 صفحه اولVitamin K2 Monograph
Introduction Vitamin K is a fat-soluble vitamin essential for the functioning of several proteins involved in blood clotting.1 Discovered in 1929 by Danish scientist Henrik Dam, the vitamin received the letter “K” because the initial discoveries were reported in a German journal in which the substance was designated as “Koagulationsvitamin.” Research during the last 30 years has resulted in gre...
