Divalent metal ions play a crucial role in catalysis by many RNA and protein enzymes that carry out phosphoryl transfer reactions, and defining their interactions with substrates is critical for understanding the mechanism of biological phosphoryl transfer. Although a vast amount of structural work has identified metal ions bound at the active site of many phosphoryl transfer enzymes, the numbe...

Pyruvate, phosphate dikinase (EC 2-7-9-1) catalyzes formation of phosphoenolpyruvate, AMP, and inorganic pyrophosphate from pyruvate, ATP, and orthophosphate. A pyrophosphoryl and phosphoryl form of the enzyme is involved in this transfer. The [32P]phosphoryl form of pyruvate, phosphate dikinase was prepared with enzyme isolated from Bacteroides symbiosus. The [32P]phosphoryl enzyme was found t...

BACKGROUND Phosphoryl transfer, typically involving high energy phosphate donors such as ATP, is the most common class of biological reactions. Despite this, the transition state for phosphoryl transfer from ATP in solution has not been systematically investigated. Characterization of the transition state for the uncatalyzed hydrolysis of ATP would provide a starting point for dissection of enz...

The influence of organic compounds on the process electrochemical nickel plating is considered. It shown that organoelement can be used as additives in electrolytes. proposed to investigate pyridine phosphoryl derivatives leveling and gloss-forming

Simple zwitterions used as auxiliary agents might have the potential to change zeta of oil-in-water (o/w) nanoemulsions on mucosa. The zwitterion phosphorylated tyramine (p-Tyr) was synthesized by phosphorylation Boc-tyramine (Boc-Tyr) using phosphoryl chloride (POCl3). It incorporated with 2% (m/v) in a self-emulsifying lipophilic phase comprising Captex 35, Cremophor EL, Capmul MCM and glycer...

Rat liver microsomal glucose 6-phosphatase catalyses phosphoryl transfer between D-glucose 6-[(R)-16O,17O,18O]phosphate and D-glucose with retention of configuration at the phosphorus atom. Since individual phosphoryl-transfer steps appear in general to occur with inversion of configuration, this observation is most simply interpreted in terms of a double-displacement mechanism with a phosphory...
