Asymmetric/Biological Unit(hide GO term definitions)

Chain A,B,C,D,E,F,G,H,I,J (CYNS_ECOLI | P00816)

molecular function
	GO:0003677	DNA binding	Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid).
	GO:0008824	cyanate hydratase activity	Catalysis of the reaction: cyanate + H2O = carbamate.
	GO:0016829	lyase activity	Catalysis of the cleavage of C-C, C-O, C-N and other bonds by other means than by hydrolysis or oxidation, or conversely adding a group to a double bond. They differ from other enzymes in that two substrates are involved in one reaction direction, but only one in the other direction. When acting on the single substrate, a molecule is eliminated and this generates either a new double bond or a new ring.
biological process
	GO:0009440	cyanate catabolic process	The chemical reactions and pathways resulting in the breakdown of cyanate, NCO-, the anion of cyanic acid.
	GO:0009439	cyanate metabolic process	The chemical reactions and pathways involving cyanate, NCO-, the anion of cyanic acid.
cellular component
	GO:0005737	cytoplasm	All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
