5 GO annotations of molecular function

Name Definition
4 iron, 4 sulfur cluster binding Binding to a 4 iron, 4 sulfur (4Fe-4S) cluster; this cluster consists of four iron atoms, with the inorganic sulfur atoms found between the irons and acting as bridging ligands.
cyclase activity Catalysis of a ring closure reaction.
iron ion binding Binding to an iron (Fe) ion.
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.
S-adenosyl-L-methionine binding Binding to S-adenosyl-L-methionine.

1 GO annotations of biological process

Name Definition
pyrroloquinoline quinone biosynthetic process The chemical reactions and pathways resulting in the formation of the cofactor pyrroloquinoline quinone (PQQ); it is synthesized from a small peptide containing tyrosine and glutamic acid; these amino acids in the peptide are multiply cross-linked and the rest of the peptide is removed.
