Catalysis of the ligation of two substances with concomitant breaking of a diphosphate linkage, usually in a nucleoside triphosphate. Ligase is the systematic name for any enzyme of EC class 6. Catalysis of the reaction: ATP + urea + CO2 = ADP + phosphate + urea-1-carboxylate. Catalysis of the reaction: GTP + IMP + L-aspartate = GDP + phosphate + N6-(1,2-dicarboxyethyl)-AMP. Catalysis of the reaction: ATP + 5-phospho-D-ribosylamine + glycine = ADP + phosphate + N1-(5-phospho-D-ribosyl)glycinamide. Catalysis of the reaction: ATP + formate + tetrahydrofolate = ADP + phosphate + 10-formyltetrahydrofolate. Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic. Catalysis of the reaction: ATP + xanthosine 5'-phosphate + NH3 = AMP + diphosphate + GMP. Catalysis of the reaction: ATP + biotin + protein = AMP + diphosphate + biotin-protein. Catalysis of the reaction: ATP + L-glutamate + methylamine = ADP + phosphate + N5-methyl-L-glutamine. Catalysis of the transfer of the amide nitrogen of glutamine to a variety of substrates. GATases catalyze two separate reactions at two active sites, which are located either on a single polypeptide chain or on different subunits. In the glutaminase reaction, glutamine is hydrolyzed to glutamate and ammonia, which is added to an acceptor substrate in the synthase reaction. Catalysis of the ligation of an acid to an amino acid via a carbon-nitrogen bond with concomitant breakage of a diphosphate linkage, usually in a nucleoside triphosphate. Catalysis of the ligation of two substances via a carbon-nitrogen bond to form a heterocyclic product, with concomitant breakage of a diphosphate linkage, usually in a nucleoside triphosphate. Catalysis of the ligation of an acid to ammonia (NH3) or an amide via a carbon-nitrogen bond with concomitant breakage of a diphosphate linkage, usually in a nucleoside triphosphate. Catalysis of a reaction that results in the formation of carbamoyl phosphate. Catalysis of the ligation of lysine onto the cytidine residue present at the wobble position (usually position 34) of an AUA-specific isoleucine tRNA, to form the derivative lysidine. This modification converts both the codon specificity of tRNA(Ile) from AUG to AUA and its amino acid specificity from methionine to isoleucine. null null Catalysis of the reaction: 5-phosphoribosyl diphosphate + imidazole-4-acetate + ATP = phosphate + pyrophosphate + 1-(5-phosphoribosyl)imidazole-4-acetate + ADP. Catalysis of the covalent attachment of the ubiquitin-like protein Atg8 to substrate molecules; phosphatidylethanolamine is a known substrate. Catalysis of the reaction: ATP + ribose 5-phosphate + NH3 = ADP + phosphate + 5-phosphoribosylamine. Catalysis of the formation of carbon-nitrogen bonds between lipoate (5-(1,2-dithiolan-3-yl)pentanoate) and a protein. Catalysis of the reaction: ATP + 5-amino-1-(5-phospho-D-ribosyl)imidazole + HCO3- = ADP + phosphate + 5-carboxyamino-1-(5-phospho-D-ribosyl)imidazole. Catalysis of the reaction: ATP + biotin-carboxyl-carrier protein + CO2 = ADP + phosphate + carboxybiotin-carboxyl-carrier protein. Catalysis of the ligation of two substances via a carbon-nitrogen bond with concomitant breakage of a diphosphate linkage, usually in a nucleoside triphosphate. Catalysis of the reaction: ATP + UTP + NH3 = ADP + phosphate + CTP. Catalysis of the reaction: ATP + formate + dihydrofolate = ADP + phosphate + 10-formyldihydrofolate. Catalysis of the reaction: ATP + L-citrulline + L-aspartate = AMP + diphosphate + (N(omega)-L-arginino)succinate.
