Sulfate or Phosphate?
November 24, 2022 by ferniglab
Some months earlier than @robField’s tweet setting off the prepare that led to the Eu sensor that discriminates PAP/PAPS, Ed Yates and myself had been having a curry with Dulce Papy-Garcia from UPEC, who had examined considered one of our PhD college students. A matter we mentioned at size was ‘why sulfate’. That’s, why does biology use each sulfate and phosphate to switch publish synthesis proteins, polysaccharides and different molecules. We didn’t provide you with a solution, however the dialog led Ed and myself to contemplate that the query merited exploration.
This we thought can be a easy matter.
It turned out to be some of the troublesome papers Ed and myself have written, to the extent that after N drafts (the place N is a considerably bigger quantity than both of us had skilled in any earlier writing train) and too many summers we nonetheless had nothing passable. So, we cunningly inveigled two colleagues, Tim Rudd from NIBSC and Marcelo Lima from Keele to hitch us on what we marketed because the sunny seaside of sulfate and phosphate, however which in actuality was a moderately dank quagmire. There’s although one thing about energy in numbers, and with very useful enter from Steve Butler in Loughborough, we arrived at what we thought-about a passable synthesis. Fortunately, the reviewers concurred, and the paper is now printed at Royal Society Interfaces, “Phosphorylation and sulfation share a standard biosynthetic pathway, however lengthen biochemical and evolutionary variety of organic macromolecules in distinct methods”.
That is certainly not the final phrase on the matter, however together with some earlier considerate papers we cite (if we have now missed one, please let me know) it supplies some concepts that will assist us to grasp why biology co-opted explicit components from the inorganic world to carry out teams of features important to life as we all know it now.
