dimethylarsinate

Three steps

• (12R)-hydroxy-(5Z,8Z,10E,14Z)-eicosatetraenoateReach from here →
  1. methylarsonous acid + S-adenosyl-L-methionine = dimethylarsinate + S-adenosyl-L-homocysteine + 2 H(+)
  2. methylarsonate + 2 glutathione + H(+) = methylarsonous acid + glutathione disulfide + H2O
  3. (12R)-hydroperoxy-(5Z,8Z,10E,14Z)-eicosatetraenoate + 2 glutathione = (12R)-hydroxy-(5Z,8Z,10E,14Z)-eicosatetraenoate + glutathione disulfide + H2O

• (5S)-hydroxy-(6E,8Z,11Z,14Z)-eicosatetraenoateReach from here →
  1. methylarsonous acid + S-adenosyl-L-methionine = dimethylarsinate + S-adenosyl-L-homocysteine + 2 H(+)
  2. methylarsonate + 2 glutathione + H(+) = methylarsonous acid + glutathione disulfide + H2O
  3. (5S)-hydroperoxy-(6E,8Z,11Z,14Z)-eicosatetraenoate + 2 glutathione = (5S)-hydroxy-(6E,8Z,11Z,14Z)-eicosatetraenoate + glutathione disulfide + H2O

• (12S)-hydroxy-(5Z,8Z,10E,14Z)-eicosatetraenoateReach from here →
  1. methylarsonous acid + S-adenosyl-L-methionine = dimethylarsinate + S-adenosyl-L-homocysteine + 2 H(+)
  2. methylarsonate + 2 glutathione + H(+) = methylarsonous acid + glutathione disulfide + H2O
  3. (12S)-hydroperoxy-(5Z,8Z,10E,14Z)-eicosatetraenoate + 2 glutathione = (12S)-hydroxy-(5Z,8Z,10E,14Z)-eicosatetraenoate + glutathione disulfide + H2O

• an S-substituted glutathioneReach from here →
  1. methylarsonous acid + S-adenosyl-L-methionine = dimethylarsinate + S-adenosyl-L-homocysteine + 2 H(+)
  2. methylarsonate + 2 glutathione + H(+) = methylarsonous acid + glutathione disulfide + H2O
  3. RX + glutathione = an S-substituted glutathione + a halide anion + H(+)

• (13S)-hydroxy-(9Z,11E)-octadecadienoateReach from here →
  1. methylarsonous acid + S-adenosyl-L-methionine = dimethylarsinate + S-adenosyl-L-homocysteine + 2 H(+)
  2. methylarsonate + 2 glutathione + H(+) = methylarsonous acid + glutathione disulfide + H2O
  3. (13S)-hydroperoxy-(9Z,11E)-octadecadienoate + 2 glutathione = (13S)-hydroxy-(9Z,11E)-octadecadienoate + glutathione disulfide + H2O

• taurochenodeoxycholateReach from here →
  1. methylarsonous acid + S-adenosyl-L-methionine = dimethylarsinate + S-adenosyl-L-homocysteine + 2 H(+)
  2. methylarsonate + 2 glutathione + H(+) = methylarsonous acid + glutathione disulfide + H2O
  3. taurochenodeoxycholate(in) + glutathione(in) + ATP + H2O = taurochenodeoxycholate(out) + glutathione(out) + ADP + phosphate + H(+)
