1 Phosphorylation of Leukotriene C4 Synthase at Serine 36 Impairs Catalytic Activity. Serine leukotriene C4 synthase Homo sapiens
2 Comparative molecular dynamics indicated that Ser(36) upon phosphorylation will pull the first luminal loop of LTC4S toward the neighboring subunit of the functional homotrimer, thereby forming hydrogen bonds with Arg(104) in the adjacent subunit. Serine leukotriene C4 synthase Homo sapiens
3 Thus, our mutational and kinetic data, together with molecular simulations, suggest that phosphorylation of Ser(36) inhibits the catalytic function of LTC4S by interference with the catalytic machinery. Serine leukotriene C4 synthase Homo sapiens
