Phosphate Esteran overview ScienceDirect Topics
In 1983 Westheimer (Why nature chose phosphates) shifted the focus on the high stability of the chemical group against hydrolytic cleavage which allow conjugating the "linking" properties of the group with the resistance need to protect the genetic information. 16 Very recently Warshel (Why nature really chose phosphates) proposed a

· Why nature chose phosphate to modify proteins. Tony Hunter. and thereby provide a means of diversifying the chemical nature of protein surfaces. A protein-linked phosphate group can form hydrogen bonds or salt bridges either intra- or intermolecularly creating stronger hydrogen bonds with arginine than either aspartate or glutamate.
The Curious Wavefunction Why nature chose phosphates
· I don t know if I have linked to this paper before but if I haven t I definitely should. It s a seminal Science paper by Frank Westheimer in which he describes his thoughts on why nature chose phosphates as the most important signaling and building blocks in living organisms. The entire paper is eminently readable and among other things Westheimer compares the properties of phosphates with

· Phosphates are nature s leaving group of choice in the biosynthesis of nearly all biological polymers including oligonucleotides proteins terpenes and carbohydrates (Fig. 1A). In rather stark contrast phosphates are very rarely employed as leaving groups in nonbiological synthesis synthetic chemists typically resort to more

All known life requires phosphorus (P) in the form of inorganic phosphate (PO4 3x or Pi) and phosphate-containing organic molecules. Pi serves as the backbone of the nucleic acids that constitute genetic material and as the major repository of chemical energy for metabolism in polyphosphate bonds. Arsenic (As) lies directly below P on the periodic table and so the two elements share many

How Prebiotic Chemistry and Early Life Chose Phosphate
The very specific thermodynamic instability and kinetic stability of phosphate esters and anhydrides impart them invaluable properties in living organisms in which highly efficient enzyme catalysts compensate for their low intrinsic reactivity. Considering their role in protein biosynthesis these properties raise a paradox about early stages How could these species be selected in the absence

Signal transduction plays a major role in life processes and in many cases these processes are controlled by the formation and dissociation of phosphate ester bonds. Thus trying to understand the general principle of signal transduction we may ask why nature chose

· In 1987 Professor F.H. Westheimer of Harvard University published what would become a widely read commentary in Science Magazine entitled "Why Nature Chose Phosphates". In it he discussed the chemical properties that make the phosphate group so ideal for the many roles that it plays in biochemistry chief among them the role of a linker

· Phosphates are hydrolases as they use the water molecule for dephosphorylation. Based on the substrate specificity phosphatases can be categorized into five classes namely tyrosine-specific phosphatases serine/threonine specific phosphatases dual specificity phosphatases histidine phosphatases and lipid phosphatases .
