Three steps

• (15R)-hydroxy-(5Z,8Z,11Z,13E,17Z)-eicosapentaenoateReach from here →
  1. transport of alanine and histidine (cytosol to extracellular)
  2. Mo-molybdopterin + L-cysteine + AH2 = thio-Mo-molybdopterin + L-alanine + A + H2O
  3. (5Z,8Z,11Z,14Z,17Z)-eicosapentaenoate + AH2 + O2 = (15R)-hydroxy-(5Z,8Z,11Z,13E,17Z)-eicosapentaenoate + A + H2O

  Catalysed by SLC7A6, MOCOS, PTGS2extracellular space, cytosol

• (11R)-hydroxy-(5Z,8Z,12E,14Z,17Z)-eicosapentaenoateReach from here →
  1. transport of alanine and histidine (cytosol to extracellular)
  2. Mo-molybdopterin + L-cysteine + AH2 = thio-Mo-molybdopterin + L-alanine + A + H2O
  3. (5Z,8Z,11Z,14Z,17Z)-eicosapentaenoate + AH2 + O2 = (11R)-hydroxy-(5Z,8Z,12E,14Z,17Z)-eicosapentaenoate + A + H2O

  1. transport of alanine and histidine (cytosol to extracellular)
  2. Mo-molybdopterin + L-cysteine + AH2 = thio-Mo-molybdopterin + L-alanine + A + H2O
  3. (7Z,10Z,13Z,16Z,19Z)-docosapentaenoate + AH2 + O2 = 13R-hydroxy-(7Z,10Z,14E,16Z,19Z)-docosapentaenoate + A + H2O

• (13S)-hydroxy-(9Z,11E)-octadecadienoateReach from here →
  1. transport of glycine and histidine (cytosol to extracellular)
  2. gamma-L-glutamyl-L-cysteine + glycine + ATP = glutathione + ADP + phosphate + H(+)
  3. (13S)-hydroperoxy-(9Z,11E)-octadecadienoate + 2 glutathione = (13S)-hydroxy-(9Z,11E)-octadecadienoate + glutathione disulfide + H2O
