Triphenyltin (TPT) is a one of the most commercially-important organotin compounds. The major use of TPT is in agriculture in fungicides to protect crops. It can detrimentally impact the environment.

Reaction A is non-enzymic, catalyzed by a microbially-associated low-molecular-weight compound called TPT-Degrading Factor (TPT-DF). TPT-DF is most likely a pyoverdine, which is a yellow-green chromopeptide siderophore with a molecular mass of 1,000 to 1,500 Da, or a pyoverdine analog (Inoue et al., 2000).

The following is a text-format Triphenyltin pathway map. An organism which can initiate the pathway is given, but other organisms may also carry out later steps. Follow the links for more information on compounds or reactions. This map is also available in graphic (4k) format.
