Evidence that class I glutamine amidotransferase, GAT1_2.1, acts as a glutaminase in roots of Arabidopsis thaliana.

Plant science : an international journal of experimental plant biology - 1 Nov 2021

Kambhampati Shrikaar, Pajak Aga, Marsolais Frédéric

Abstract excerpt

The glutamine amidotransferase gene GAT1_2.1 is a marker of N status in Arabidopsis root, linked to a shoot branching phenotype. The protein has an N-terminal glutamine amidotransferase domain and a C-terminal extension with no recognizable protein domain. A purified, recombinant version of the glutamine amidotransferase domain was catalytically active as a glutaminase, with apparent Km value of 0.66 mM and Vmax...
