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.
