Synthesis of unsaturated phosphatidylinositol 4-phosphates and the effects of substrate unsaturation on SopB phosphatase activity

10 February, 2015 - 12:54

Org. Biomol. Chem., 2015, 13,2001-2011
DOI: 10.1039/C4OB02258K, PaperSamuel Furse, LokHang Mak, Edward W. Tate, Richard H. Templer, Oscar Ces, Rudiger Woscholski, Piers R. J. Gaffney
Single enantiomers of PI-4-P, with a range of sn-2-fatty acid esters, were prepared efficiently. The effects of the degree of sn-2-unsaturation on the kinetic parameters of SopB were determined.
