estrone 3-sulfate

Three steps

• 19-hydroxyprostaglandin H2Reach from here →
  1. transport of estrone 3-sulfate (cytosol to extracellular)
  2. transport of prostaglandin H2 (cytosol to extracellular)
  3. prostaglandin H2 + reduced [NADPH--hemoprotein reductase] + O2 = 19-hydroxyprostaglandin H2 + oxidized [NADPH--hemoprotein reductase] + H2O + H(+)

  Catalysed by SLCO1B1, CYP4F8extracellular space, cytosol

• 15-hydroperoxy-(5Z,8Z,11Z,13E)-eicosatetraenoateReach from here →
  1. transport of estrone 3-sulfate (cytosol to extracellular)
  2. transport of arachidonate (cytosol to extracellular)
  3. (5Z,8Z,11Z,14Z)-eicosatetraenoate + O2 = 15-hydroperoxy-(5Z,8Z,11Z,13E)-eicosatetraenoate

  Catalysed by SLCO1B1, ALOX15Bextracellular space, cytosol

• 5-hydroperoxy-(6E,8Z,11Z,14Z)-eicosatetraenoateReach from here →
  1. transport of estrone 3-sulfate (cytosol to extracellular)
  2. transport of arachidonate (cytosol to extracellular)
  3. (5Z,8Z,11Z,14Z)-eicosatetraenoate + O2 = 5-hydroperoxy-(6E,8Z,11Z,14Z)-eicosatetraenoate
