Visualizing complexes of phospholipids with Streptomyces phospholipase D by automated docking.
C.L.Aikens, A.Laederach, P.J.Reilly.
The automated docking program AutoDock was used to dock nine phosphatidic acids (PAs), six phosphatidylcholines, five phosphatidylethanolamines, four phosphatidylglycerols, one phosphatidylinositol and two phosphatidylserines, which have two identical saturated fatty acid residues with an even numbers of carbon atoms, onto the active site of Streptomyces sp. PMF phospholipase D (PLD). Two PAs with one double bond on the fatty acid chain linked to the C2 of the glycerol residue were also docked. In general, binding energies become progressively more negative as fatty acid residues become longer. When these residues are of sufficient length, one is coiled against a hydrophobic cliff in a well that also holds the glycerol and phosphate residues and the head group, while the other generally is bound by a hydrophobic surface outside the well. Phosphatidylcholines have the only head group that is firmly bound by the active site, giving a possible structural explanation for the low selectivity of Streptomyces PLD for other phospholipid substrates.

Figure 5. Space-filling illustrations of the docking of (a) PA-14 and PA-14:1 and (b) PA-18 and PA-18:1 in the PLD active site. Hydrophobic (white), negatively-charged (red), and positively-charged (blue) surfaces. The positive surface at the center of the illustrations is composed of the putative catalytic residues His165 and His438, as well as Lys167 and Lys440. The hydrophobic cliff is at the bottom of the illustrations.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time.
