Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at transcript leveli

Functioni

Essential for nitrogen assimilation, distribution and remobilization within the plant via the phloem.By similarity

Catalytic activityi

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

Pathway:iL-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. Asparagine synthetase [glutamine-hydrolyzing] (ASN1)
This subpathway is part of the pathway L-asparagine biosynthesis, which is itself part of Amino-acid biosynthesis.
