Chain A,B,C,D,E,F,G,H (PTR1_LEIMA | Q01782)

molecular function
	GO:0016491	oxidoreductase activity	Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced.
	GO:0047040	pteridine reductase activity	Catalysis of the reaction: 5,6,7,8-tetrahydrobiopterin + 2 NADP(+) = biopterin + 2 H(+) + 2 NADPH.
	GO:0004799	thymidylate synthase activity	Catalysis of the reaction: 5,10-methylenetetrahydrofolate + dUMP = 7,8-dihydrofolate + thymidylate.
biological process
	GO:0034599	cellular response to oxidative stress	Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of oxidative stress, a state often resulting from exposure to high levels of reactive oxygen species, e.g. superoxide anions, hydrogen peroxide (H2O2), and hydroxyl radicals.
	GO:0032259	methylation	The process in which a methyl group is covalently attached to a molecule.
	GO:0055114	oxidation-reduction process	A metabolic process that results in the removal or addition of one or more electrons to or from a substance, with or without the concomitant removal or addition of a proton or protons.
	GO:0019889	pteridine metabolic process	The chemical reactions and pathways involving pteridine, pyrazino(2,3-dipyrimidine), the parent structure of pterins and the pteroyl group.
	GO:0031427	response to methotrexate	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 methotrexate stimulus. Methotrexate is 4-amino-10-methylformic acid, a folic acid analogue that is a potent competitive inhibitor of dihydrofolate reductase.
	GO:0006729	tetrahydrobiopterin biosynthetic process	The chemical reactions and pathways resulting in the formation of tetrahydrobiopterin, the reduced form of biopterin (2-amino-4-hydroxy-6-(1,2-dihydroxypropyl)-pteridine). It functions as a hydroxylation coenzyme, e.g. in the conversion of phenylalanine to tyrosine.
