Theoretical Model(hide GO term definitions)
Chain A   (PANC_AQUAE | O67891)
molecular function
    GO:0005524    ATP binding    Interacting selectively and non-covalently with ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
    GO:0003824    catalytic activity    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.
    GO:0016874    ligase activity    Catalysis of the joining of two substances, or two groups within a single molecule, with the concomitant hydrolysis of the diphosphate bond in ATP or a similar triphosphate.
    GO:0000166    nucleotide binding    Interacting selectively and non-covalently with a nucleotide, any compound consisting of a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the ribose or deoxyribose.
    GO:0004592    pantoate-beta-alanine ligase activity    Catalysis of the reaction: ATP + (R)-pantoate + beta-alanine = AMP + diphosphate + (R)-pantothenate.
biological process
    GO:0009058    biosynthetic process    The chemical reactions and pathways resulting in the formation of substances; typically the energy-requiring part of metabolism in which simpler substances are transformed into more complex ones.
    GO:0015940    pantothenate biosynthetic process    The chemical reactions and pathways resulting in the formation of pantothenate, the anion of pantothenic acid. It is a B complex vitamin that is a constituent of coenzyme A and is distributed ubiquitously in foods.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
