CC   -!- FUNCTION: Catalyzes the addition of molecular CO(2) and H(2)O to
CC       ribulose 1,5-bisphosphate (RuBP), generating two molecules of 3-
CC       phosphoglycerate (3-PGA). Functions in an archaeal AMP degradation
CC       pathway, together with AMP phosphorylase and R15P isomerase.
CC       {ECO:0000256|HAMAP-Rule:MF_01133}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2 (2R)-3-phosphoglycerate + 2 H(+) = CO2 + D-ribulose 1,5-
CC         bisphosphate + H2O; Xref=Rhea:RHEA:23124, ChEBI:CHEBI:15377,
CC         ChEBI:CHEBI:15378, ChEBI:CHEBI:16526, ChEBI:CHEBI:57870,
CC         ChEBI:CHEBI:58272; EC=4.1.1.39; Evidence={ECO:0000256|HAMAP-
CC         Rule:MF_01133};
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=D-ribulose 1,5-bisphosphate + O2 = (2R)-3-phosphoglycerate +
CC         2-phosphoglycolate + 2 H(+); Xref=Rhea:RHEA:36631, ChEBI:CHEBI:15378,
CC         ChEBI:CHEBI:15379, ChEBI:CHEBI:57870, ChEBI:CHEBI:58033,
CC         ChEBI:CHEBI:58272; Evidence={ECO:0000256|HAMAP-Rule:MF_01133};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000256|HAMAP-
CC         Rule:MF_01133};
CC       Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000256|HAMAP-Rule:MF_01133};
CC   -!- SUBUNIT: Homodimer or homodecamer. In contrast to form I RuBisCO, the
CC       form III RuBisCO is composed solely of large subunits.
CC       {ECO:0000256|HAMAP-Rule:MF_01133}.
CC   -!- MISCELLANEOUS: Because the Archaea possessing a type III RuBisCO are
CC       all anaerobic, it is most likely that only the carboxylase activity of
CC       RuBisCO, and not the competitive oxygenase activity (by which RuBP
CC       reacts with O(2) to form one molecule of 3-phosphoglycerate and one
CC       molecule of 2-phosphoglycolate), is biologically relevant in these
CC       strains. {ECO:0000256|HAMAP-Rule:MF_01133}.
CC   -!- SIMILARITY: Belongs to the RuBisCO large chain family. Type III
CC       subfamily. {ECO:0000256|HAMAP-Rule:MF_01133}.
