    Functioni

    Catalyzes the first reaction in the primary pathway for the renal catabolism of glutamine. Plays a role in maintaining acid-base homeostasis. Regulates the levels of the neurotransmitter glutamate in the brain. Isoform 2 lacks catalytic activity.

    Catalytic activityi

    L-glutamine + H2O = L-glutamate + NH3.1 Publication

    Enzyme regulationi

    Isoform 1 and isoform 3 are activated by phosphate. Inhibited by BPTES. BPTES binds between subunits and favors dissociation of the tetramer into dimers.1 Publication

    Miscellaneousi

    Caution

    Isoform 3 is predicted to be expressed at very low levels due to a premature stop codon in the mRNA, leading to nonsense-mediated mRNA decay (PubMed:14759258), but has been shown to be well expressed (PubMed:17940881 and PubMed:11015561) and the encoded protein is detected in mitochondria (PubMed:22228304).2 Publications
    A report observed N-glycosylation at Asn-620 (PubMed:19139490). However, as the protein is mitochondrial, additional evidences are required to confirm this result.1 Publication
