Regulation of proline oxidase activity by lactate.
We found that proline oxidase, the first enzyme of the proline degradative pathway, is inhibited by lactate. The Km of the enzyme for proline increases with increasing concentrations of lactate. Since proline can be a source for gluconeogenesis, regulation of proline degradation by lactate may serve as a mechanism for allocation of metabolic fuel sources. The marked inhibition of proline oxidas...
متن کاملRegulation of Kir2.1 Function Under Shear Stress and Cholesterol Loading
L ining the innermost layer of blood vessels, the endothelium is in direct contact with circulating blood elements and, consequently, is affected by mechanical forces generated by blood flow. Among these forces, fluid shear stress site-specifically regulates endothelial cells (ECs): In regions where the flowing blood is multidirectional (low shear stress or disturbed flow), ECs are activated an...
متن کاملProline Oxidase and Water Stress-induced Proline Accumulation in Spinach Leaves.
Spinach (Spinacia oleracea L.) leaf discs accumulated free proline when exposed to polyethylene glycol solutions of water potential less than -10 bars. At -20 bars, the accumulation was 11 micromoles per gram original fresh weight in a 24-hour period.When the leaf organelles were separated on a sucrose gradient, a proline oxidase was detected in the mitochondrial fraction. Isolated mitochondria...
متن کاملNADPH oxidase AtrbohD and AtrbohF function in ROS-dependent regulation of Na⁺/K⁺homeostasis in Arabidopsis under salt stress.
Maintaining cellular Na(+)/K(+) homeostasis is pivotal for plant survival in saline environments. However, knowledge about the molecular regulatory mechanisms of Na(+)/K(+) homeostasis in plants under salt stress is largely lacking. In this report, the Arabidopsis double mutants atrbohD1/F1 and atrbohD2/F2, in which the AtrbohD and AtrbohF genes are disrupted and generation of reactive oxygen s...
متن کاملRegulation of levels of proline as an osmolyte in plants under water stress.
Compatible osmolytes are potent osmoprotectants that play a role in counteracting the effects of osmotic stress. Proline (Pro) is one of the most common compatible osmolytes in water-stressed plants. The accumulation of Pro in dehydrated plants is caused both by activation of the biosynthesis of Pro and by inactivation of the degradation of Pro. In plants, L-Pro is synthesized from L-glutamic a...
