Asymmetric/Biological Unit(hide GO term definitions)

Chain A (DHPS_ECOLI | P0AC13)

molecular function
	GO:0004156	dihydropteroate synthase activity	Catalysis of the reaction: 2-amino-4-hydroxy-6-hydroxymethyl-7,8-dihydropteridine diphosphate + 4-aminobenzoate = diphosphate + dihydropteroate.
	GO:0046872	metal ion binding	Interacting selectively and non-covalently with any metal ion.
	GO:0016740	transferase activity	Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2.
biological process
	GO:0044237	cellular metabolic process	The chemical reactions and pathways by which individual cells transform chemical substances.
	GO:0046656	folic acid biosynthetic process	The chemical reactions and pathways resulting in the formation of folic acid, pteroylglutamic acid.
	GO:0009396	folic acid-containing compound biosynthetic process	The chemical reactions and pathways resulting in the formation of folic acid and its derivatives.
	GO:0042558	pteridine-containing compound metabolic process	The chemical reactions and pathways involving any compound containing pteridine (pyrazino(2,3-dipyrimidine)), e.g. pteroic acid, xanthopterin and folic acid.
	GO:0042493	response to drug	Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a drug stimulus. A drug is a substance used in the diagnosis, treatment or prevention of a disease.
	GO:0046654	tetrahydrofolate biosynthetic process	The chemical reactions and pathways resulting in the formation of tetrahydrofolate, 5,6,7,8-tetrahydrofolic acid, a folate derivative bearing additional hydrogens on the pterin group.
cellular component
	GO:0005737	cytoplasm	All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
	GO:0005829	cytosol	The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
