Vitamin K and oxidative phosphorylation.
1. Oxidative phosphorylation was studied in a cell-free preparation of Mycobacterium phlei and in rat-liver mitochondria. Phosphorylation was destroyed in both systems by long-wave ultraviolet radiation and restored by the addition of small amounts of [2-Me-(14)C,(3)H]phylloquinone. When the radioactive quinones were recovered from the phosphorylating system and chromatographed with carrier phy...
متن کاملOn the role of K+ on oxidative phosphorylation.
The influence of K+ on oxidative phosphorylation of rat liver mitochondria has been investigated. Fresh mitochondria undergo a loss of respiratory control concomitantly with the loss of K+, and a rough correlation was found between the K+ content of the mitochondria and the State 3 to State 4 respiratory ratio. K+-depleted mitochondria have a low respiratory control with NAD-dependent substrate...
متن کاملBarbiturates and oxidative phosphorylation.
It has been claimed that barbiturates uncouple oxidative phosphorylations (Brody & Bain, 1954; Brody, 1955). These authors have demonstrated that during the oxidation of pyruvate by liver and brain mitochondria, phosphate uptake was lowered proportionately more than oxygen uptake. Support for the uncoupling theory was derived from certain similarities between the barbiturates and 2:4dinitrophen...
متن کاملVitamin K Metabolism and Vitamin K-Dependent Proteins
"The law should keep the parties off-balance, uncertain about the precise measure of their power or impotence regarding one another, in order to counterbalance the impulse toward destructively stereotypical choicemaking/choiceless role allocations that inevitably arise from the stressful confusions of their situation." The medium for Professor Burt's message is a series of in-depth psychologica...
متن کاملA case report of temporary and acquired vitamin K-dependent clotting factor deficiency without any response to administrated vitamin K
Abstract Background and Objectives Vitamin K-dependent clotting factor deficiency (VKCFD) is usually an acquired problem due to liver disease, malabsorption, and overdose of warfarin. In the present paper the significance and role of vitamin K-dependent coagulation factors in menorrhagia were evaluated. Case We present a rare case of 43 year woman with acquired vitamin K deficiency and se...
