Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Catalyzes the attachment of serine to tRNA(Ser). Is also able to aminoacylate tRNA(Sec) with serine, to form the misacylated tRNA L-seryl-tRNA(Sec), which will be further converted into selenocysteinyl-tRNA(Sec).UniRule annotation

Catalytic activityi

ATP + L-serine + tRNA(Ser) = AMP + diphosphate + L-seryl-tRNA(Ser).UniRule annotation
ATP + L-serine + tRNA(Sec) = AMP + diphosphate + L-seryl-tRNA(Sec).UniRule annotation

Pathway: selenocysteinyl-tRNA(Sec) biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes L-seryl-tRNA(Sec) from L-serine and tRNA(Sec).UniRule annotation
Proteins known to be involved in this subpathway in this organism are:
  1. Serine--tRNA ligase (serS)
This subpathway is part of the pathway selenocysteinyl-tRNA(Sec) biosynthesis, which is itself part of Aminoacyl-tRNA biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes L-seryl-tRNA(Sec) from L-serine and tRNA(Sec), the pathway selenocysteinyl-tRNA(Sec) biosynthesis and in Aminoacyl-tRNA biosynthesis.

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.
