Reaction: An unknown oxidase oxidises D-UBGN to UBN
- in pathway: Heme degradation
The D urobilinogen (D UBGN) that remains in the intestine is directly reduced to stercobilin (STBN) or oxidised to urobilin (UBN), a yellow pigment seen in urine (Rupe & Fetter 1981). How this oxidation is mediated is unknown (Hamoud et al. 2018).
Reaction - small molecule participants:
UBN [extracellular region]
a reduced electron acceptor [extracellular region]
D-UBGN [extracellular region]
an oxidized electron acceptor [extracellular region]
