Organism
Thermotoga maritima (strain ATCC 43589 / MSB8 / DSM 3109 / JCM 10099)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Catalytic activityi

Carbamoyl phosphate + L-aspartate = phosphate + N-carbamoyl-L-aspartate.

Pathwayi: UMP biosynthesis via de novo pathway

This protein is involved in step 2 of the subpathway that synthesizes (S)-dihydroorotate from bicarbonate.
Proteins known to be involved in the 3 steps of the subpathway in this organism are:
  1. Carbamoyl-phosphate synthase large chain (carB), Carbamoyl-phosphate synthase small chain (carA), Carbamoyl-phosphate synthase (glutamine-hydrolyzing) (Tmari_0554), Carbamoyl-phosphate synthase small chain (carA)
  2. Protein PyrBI (pyrBI)
  3. Dihydroorotase (pyrC), Dihydroorotase (pyrC)
This subpathway is part of the pathway UMP biosynthesis via de novo pathway, which is itself part of Pyrimidine metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes (S)-dihydroorotate from bicarbonate, the pathway UMP biosynthesis via de novo pathway and in Pyrimidine metabolism.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
