label: carbon-nitrogen ligase activity, with glutamine as amido-N-donor
label_lc: carbon-nitrogen ligase activity, with glutamine as amido-n-donor
description: "Catalysis of the transfer of the amide nitrogen of glutamine to a substrate. Usually composed of two subunits or domains, one that first hydrolyzes glutamine, and then transfers the resulting ammonia to the second subunit (or domain), where it acts as a source of nitrogen."
