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;
CC Evidence={ECO:0000256|HAMAP-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}.
