D-arginine

Three steps

• thio-Mo-molybdopterinReach from here →
  1. D-arginine(in) + L-ornithine(out) = D-arginine(out) + L-ornithine(in)
  2. transport of cysteine and ornithine (cytosol to extracellular)
  3. Mo-molybdopterin + L-cysteine + AH2 = thio-Mo-molybdopterin + L-alanine + A + H2O

  Catalysed by SLC25A2, SLC7A6, MOCOSinner side of the membrane, outer side of the membrane, extracellular space, cytosol

• glycodeoxycholateReach from here →
  1. D-arginine(in) + L-ornithine(out) = D-arginine(out) + L-ornithine(in)
  2. L-Arginine:glycine amidinotransferase
  3. Glycodeoxycholate amidohydrolase

• N-tetradecanoylglycineReach from here →
  1. D-arginine(in) + L-ornithine(out) = D-arginine(out) + L-ornithine(in)
  2. L-Arginine:glycine amidinotransferase
  3. tetradecanoyl-CoA + glycine = N-tetradecanoylglycine + CoA + H(+)
