Proteins known to be involved in the 3 steps of the subpathway in this organism are:
  1. no protein annotated in this organism
  2. Argininosuccinate synthase (ass1)
  3. no protein annotated in this organism
This subpathway is part of the pathway L-arginine biosynthesis, which is itself part of Amino-acid biosynthesis.

Pathwayi: urea cycle

This protein is involved in step 1 of the subpathway that synthesizes (N(omega)-L-arginino)succinate from L-aspartate and L-citrulline.
Proteins known to be involved in this subpathway in this organism are:
  1. Argininosuccinate synthase (ass1)
This subpathway is part of the pathway urea cycle, which is itself part of Nitrogen 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.
