A continuous spectrophotometric assay for phosphate releasing enzymes
… UV-spectrophotometric assay is described for two phosphate releasing enzymes, aspartate transcarbamylase and ATPase of Herpes Simplex Virus. Phosphate release is coupled to the phosphorolysis of the nucleoside analogue 7-methylinosine catalyzed by purine nucleoside phosphorylase. When this …

Analysis of water quality problems in the VPI & SU Duck Ponds and suggested management alternatives
… to the bottom and afterwards, lowered othophosphate-phosphorus concentrations below 10 µg/L in the water column. The longevity of the one-time treatment in reducing the sediment-phosphate release rate is unknown because the monitoring program was not continued beyond July of 1988. A …

Laboratory Testing of Process Controls for the Mitigation of Toxic Shock Events at Enhanced Biological Phosphorus Removal Wastewater Treatment Plants
… as indicated by rates of respiration and phosphate release and uptake. The shock event and corrective action strategy both inhibited EBPR. After an initial perturbation, the positive control matched the performance of the negative control. The corrective action, however, exhibited …

Effects of sediment on water quality in the Occoquan Reservoir
… in the Occoquan Reservoir on the water quality. Phosphate determination by the ascorbic acid method was first evaluated for its precision and accuracy. An assay was developed to measure the rate of nutrient phosphate release to the overlying water in a quiescent dark condition. The assay was …

DROSOPHILA CLASS-I MYOSINS THAT CAN IMPACT LEFT-RIGHT ASYMMETRY HAVE DISTINCT ATPASE KINETICS
… We discovered myo1C has a rate-limiting phosphate release followed by slow MgADP release, dwelling in the cycle for longer periods, suggesting its function as a molecular tether. Contrarily, myo1D has a rate-limiting MgADP release and can power small unilamellar vesicle transport, …

Opportunities for Nutrient Recovery from Post-Digestion Sludge Handling: Analysis and Feasibility Study Using Municipal Scale Aerobic and Anaerobic Digesters
… of struvite precipitation by addition of phosphate and magnesium compounds is evaluated through batch reaction using anaerobic sludge filtrate. Aerobic sludge contains most of the nutrient resources in the solid phase, ready for recovery if handled properly. Phosphorus release is a …

Shelf biogeochemical interactions and feedback processes in the Benguela upwelling system
… from BFM show higher nitrogen uptake rates than phosphate in shelf and offshore stations. The uptake rates are high on the shallow shelf due to luxury nutrient uptake. High N:P ratios occur at the stations at 21ᵒS than off Walvis Bay and are attributed to the presence of nutrient-rich, oxygen …

Structural Mechanisms of F-actin Mechanochemical Regulation and Flexible Network Assembly
… which persists for minutes before phosphate release to yield long-lived ADP–F-actin. I determined cryo-EM structures of both ADP–F-actin and ADP-Pi–F-actin with sufficient resolution (~2.4 Å) to confidently build atomic models including solvent, which showed the two states to be …
