UniProtKB - Q9LVM5 (TTHL_ARATH)
Protein
Uric acid degradation bifunctional protein TTL
Gene
TTL
Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Functioni
Involved in the last two steps of the degradation of uric acid, i.e. the hydrolysis of 5-hydroxyisourate (HIU) to 2-oxo-4-hydroxy-4-carboxy-5-ureidoimidazoline (OHCU) and its stereoselective decarboxylation to (S)-allantoin. Might function as a negative regulator to modulate brassinosteroid-mediated plant growth.
Catalytic activityi
: urate degradation Pathwayi
This protein is involved in step 2 and 3 of the subpathway that synthesizes (S)-allantoin from urate.Proteins known to be involved in the 3 steps of the subpathway in this organism are:
- Uricase (C24_LOCUS8867), Urate oxidase (AXX17_At2g19490), Uricase (At2g26230), Uricase (AN1_LOCUS9015), Uricase (AXX17_At2g22060)
- Uric acid degradation bifunctional protein TTL (TTL)
- Uric acid degradation bifunctional protein TTL (TTL)
View all proteins of this organism that are known to be involved in the subpathway that synthesizes (S)-allantoin from urate, the pathway urate degradation and in Purine metabolism.
