Catalytic decomposition of phosphorus compounds to produce phosphorus atoms

Phosphorus Compounds in Animal Tissues

The concept that nucleic acids are intimately associated with fundamental cellular processes has gained considerable favor within the last few years. This can undoubtedly be attributed to the researches of Caspersson and his associates. Caspersson, with the aid of ultraviolet spectrophotometry, has been able to measure the nucleic acids in various parts of the cell under a variety of experiment...

Phosphorus Compounds in the Cell

In the first paper in this series (Davidson, Frazer & Hutchison, 1951) it was emphasized that in experiments on the incorporation of radioactive phosphorus (32p) into the nucleic acids and their derivatives in the cell, it was essential, in order to obtain true specific activities, to separate the nucleotide fractions in a form free from all traces of highly active contaminants. The procedure o...

Phosphorus transformations during decomposition of wetland macrophytes.

The microbially mediated transformation of detrital P entering wetlands has important implications for the cycling and long-term sequestration of P in wetland soils. We investigated changes in P forms in sawgrass (Cladium jamaicense Crantz) and cattail (Typha domingensis Pers.) leaf litter during 15 months of decomposition at two sites of markedly different nutrient status within a hard-water s...

Phosphatase Hydrolysis of Organic Phosphorus Compounds

Phosphatases are diverse groups of enzymes that deserve special attention because of their significant roles in organic phosphorus (OP) mineralization to inorganic available forms (Pi). This work 1) compared the catalytic potentials of commercially acid phosphatase from wheat germ, sweet potato, and potato, and alkaline phosphatase from E. coli; 2) demonstrated that the rate of hydrolysis, cata...
