prostaglandin F2alpha

Three steps

• (18R)-hydroxy-(5Z,8Z,11Z,14Z)-eicosatetraenoateReach from here →
  1. transport of prostaglandin F2alpha (cytosol to extracellular)
  2. transport of arachidonate (cytosol to extracellular)
  3. (5Z,8Z,11Z,14Z)-eicosatetraenoate + reduced [NADPH--hemoprotein reductase] + O2 = (18R)-hydroxy-(5Z,8Z,11Z,14Z)-eicosatetraenoate + oxidized [NADPH--hemoprotein reductase] + H2O + H(+)

  Catalysed by SLCO1B1, CYP4F8extracellular space, cytosol

• prostaglandin H1Reach from here →
  1. transport of prostaglandin F2alpha (cytosol to extracellular)
  2. transport of prostaglandin E1 (cytosol to extracellular)
  3. prostaglandin-E synthase (prostaglandin E1)

  Catalysed by SLCO1B1, PTGES, PTGES3, PTGES2extracellular space, cytosolOne of 2 routes

• 15-hydroperoxy-(5Z,8Z,11Z,13E)-eicosatetraenoateReach from here →
  1. transport of prostaglandin F2alpha (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 prostaglandin F2alpha (cytosol to extracellular)
  2. transport of arachidonate (cytosol to extracellular)
  3. (5Z,8Z,11Z,14Z)-eicosatetraenoate + O2 = 5-hydroperoxy-(6E,8Z,11Z,14Z)-eicosatetraenoate

  Catalysed by SLCO1B1, ALOX15Bextracellular space, cytosol

• 2-(1-hydroxyethyl)thiamine diphosphateReach from here →
  1. prostaglandin F2alpha(out) + 2 (S)-lactate(in) = prostaglandin F2alpha(in) + 2 (S)-lactate(out)
  2. (S)-lactate + NAD(+) = pyruvate + NADH + H(+)
  3. pyruvate:thiamin diphosphate acetaldehydetransferase (decarboxylating)
