Chain A,B,C,D,E,F (DCD_ECOLI | P28248)

molecular function
	GO:0008829	dCTP deaminase activity	Catalysis of the reaction: dCTP + H2O = dUTP + NH3.
	GO:0016787	hydrolase activity	Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3.
biological process
	GO:0006226	dUMP biosynthetic process	The chemical reactions and pathways resulting in the formation of dUMP, deoxyuridine monophosphate (2'-deoxyuridine 5'-phosphate).
	GO:0006229	dUTP biosynthetic process	The chemical reactions and pathways resulting in the formation of dUTP, deoxyuridine (5'-)triphosphate.
	GO:0046080	dUTP metabolic process	The chemical reactions and pathways involving dUTP, deoxyuridine (5'-)triphosphate.
	GO:0015949	nucleobase-containing small molecule interconversion	The chemical reactions and pathways by which a nucleobase, nucleoside or nucleotide small molecule is synthesized from another nucleobase, nucleoside or nucleotide small molecule.
	GO:0009117	nucleotide metabolic process	The chemical reactions and pathways involving a nucleotide, a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the glycose moiety; may be mono-, di- or triphosphate; this definition includes cyclic nucleotides (nucleoside cyclic phosphates).
	GO:0009220	pyrimidine ribonucleotide biosynthetic process	The chemical reactions and pathways resulting in the formation of a pyrimidine ribonucleotide, a compound consisting of nucleoside (a pyrimidine base linked to a ribose sugar) esterified with a phosphate group at either the 3' or 5'-hydroxyl group of the sugar.
cellular component
	GO:0005829	cytosol	The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
