Chain A (CAS1_STRC2 | Q05581)

molecular function
	GO:0033758	clavaminate synthase activity	Catalysis of the reactions: deoxyamidinoproclavaminate + 2-oxoglutarate + O2 = amidinoproclavaminate + succinate + CO2 + H2O; proclavaminate + 2-oxoglutarate + O2 = dihydroclavaminate + succinate + CO2 + 2 H2O; and dihydroclavaminate + 2-oxoglutarate + O2 = clavaminate + succinate + CO2 + 2 H2O.
	GO:0005506	iron ion binding	Interacting selectively and non-covalently with iron (Fe) ions.
	GO:0046872	metal ion binding	Interacting selectively and non-covalently with any metal ion.
	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.
biological process
	GO:0017000	antibiotic biosynthetic process	The chemical reactions and pathways resulting in the formation of an antibiotic, a substance produced by or derived from certain fungi, bacteria, and other organisms, that can destroy or inhibit the growth of other microorganisms.
	GO:0033050	clavulanic acid biosynthetic process	The chemical reactions and pathways resulting in the formation of clavulanic acid, (2R,3Z,5R)-3-(2-hydroxyethylidene)-7-oxo-4-oxa-1-azabicyclo[3.2.0]heptane-2-carboxylic acid.
	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.
