Journal of bacteriology, 169(2), 710-717 (1987-02-01)
Carbon-phosphorus bond cleavage activity, found in bacteria that utilize alkyl- and phenylphosphonic acids, has not yet been obtained in a cell-free system. Given this constraint, a systematic examination of in vivo C-P lyase activity has been conducted to develop insight

The mechanism of nucleation, steady-state growth, and repair is investigated for an oxygen evolving catalyst prepared by electrodeposition from Co(2+) solutions in weakly basic electrolytes (Co-OEC). Potential step chronoamperometry and atomic force microscopy reveal that nucleation of Co-OEC is progressive

The intracellular pH of Escherichia coli cells, respiring on endogenous energy sources, was monitored continuously by 31P NMR over an extracellular pH range between 5.5 and 9. pH homeostasis was found to be good over the entire range, with the

The toxicity of herbicides to animals and human is an issue of worldwide concern. The present study was undertaken to evaluate toxic potential of widely used pesticide - glyphosate, its metabolites: aminomethylphosphonic acid (AMPA); methylphosphonic acid and its impurities: N-(phosphonomethyl)iminodiacetic

A new two-step high-performance liquid chromatography (HPLC) procedure has been developed to separate modified histone H1 subtypes. Reversed-phase (RP) HPLC followed by hydrophilic-interaction liquid chromatography (HILIC) was used for analytical and semi-preparative scale fractionation of multi-phosphorylated H1 histone subtypes into
