Pathway: taurine biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes hypotaurine from L-cysteine.
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Cysteine dioxygenase (CDO)
  2. no protein annotated in this organism
This subpathway is part of the pathway taurine biosynthesis, which is itself part of Organosulfur biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes hypotaurine from L-cysteine, the pathway taurine biosynthesis and in Organosulfur biosynthesis.

Cross-linki102 ↔ 1783'-(S-cysteinyl)-tyrosine (Cys-Tyr)By similarity

Post-translational modificationi

The thioether cross-link between Cys-102 and Tyr-178 plays a structural role through stabilizing the Fe2+ ion, and prevents the production of highly damaging free hydroxyl radicals by holding the oxygen radical via hydroxyl hydrogen.By similarity

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 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.
