Structure of 3,4-Dihydroxy-2-butanone 4-Phosphate Synthase from Methanococcus jannaschii in Complex with Divalent Metal Ions and the Substrate Ribulose 5-Phosphate: implications for the catalytic mechanism [PDF]

open access: yes, 2003
Skeletal rearrangements of carbohydrates are crucial for many biosynthetic pathways. In riboflavin biosynthesis ribulose 5-phosphate is converted into 3,4-dihydroxy-2-butanone 4-phosphate while its C4 atom is released as formate in a sequence of metal ...

Modified pea apyrase has altered nuclear functions and enhances the growth of yeast and Arabidopsis

open access: yesFrontiers in Plant Science
Apyrases (NTPDases) regulate growth and development in multiple eukaryotic organisms and function in multiple sub-cellular locales. An earlier report showed that the ectopic expression of psNTP9 (PS), a chromatin-associated pea (Pisum sativum) apyrase ...

Enhanced Phosphate Removal by Hydrated Lanthanum Oxide-Modified Quaternized Polyaniline Nanocomposite: Performance and Mechanism

open access: yesSustainable Chemistry
Phosphorus mainly exists in the form of phosphate in water. Excessive phosphorus can cause eutrophication, leading to algae reproduction and the depletion of oxygen in water, destroying aquatic ecology.

The Economics of Manure Utilization: Model and Application [PDF]

open access: yes
A model of manure utilization is developed and applied to four types of transportable manure. Model results highlight important response differences among manure types and generally illustrate the diseconomies of manure production. For example, as manure

Changes in the forms and availability of applied phosphate over a twelve-month period in two soils of the Manawatu-Rangitikei sand country : a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science at Massey University [PDF]

open access: yes, 1972
A feature of New Zealand agriculture is the requirement for regular applications of phosphate fertilizer to maintain high producing pastures. This is reflected in the large amounts of phosphate fertilizer sold annually, which for the 1971-72 season ...
