Functioni

Catalytic activityi

ATP + L-aspartate + L-glutamine + H2O = AMP + diphosphate + L-asparagine + L-glutamate.

Pathwayi: L-asparagine biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes L-asparagine from L-aspartate (L-Gln route).
Proteins known to be involved in this subpathway in this organism are:
  1. Putative asparagine synthetase [glutamine-hydrolyzing] 1 (MJ1116), Putative asparagine synthetase [glutamine-hydrolyzing] 2 (MJ1056)
This subpathway is part of the pathway L-asparagine biosynthesis, which is itself part of Amino-acid 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 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.
