CC -!- FUNCTION: RuBisCO catalyzes two reactions: the carboxylation of D-
CC ribulose 1,5-bisphosphate, the primary event in carbon dioxide
CC fixation, as well as the oxidative fragmentation of the pentose
CC substrate. Both reactions occur simultaneously and in competition at
CC the same active site. Although the small subunit is not catalytic it is
CC essential for maximal activity. Involved in antiviral defenses (By
CC similarity). {ECO:0000250|UniProtKB:A0A0S4IJL0, ECO:0000255|HAMAP-
CC Rule:MF_00860}.
CC -!- SUBUNIT: Heterohexadecamer of 8 large and 8 small subunits.
CC {ECO:0000255|HAMAP-Rule:MF_00860}.
CC -!- SUBUNIT: (Microbial infection) Binds to tobamovirus movement protein;
CC this interaction seems required for viral systemic movement.
CC {ECO:0000305}.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast {ECO:0000255|HAMAP-
CC Rule:MF_00860}.
CC -!- SUBCELLULAR LOCATION: Cell junction, plasmodesma
CC {ECO:0000250|UniProtKB:A0A0S4IJL0}. Note=(Microbial infection) May be
CC present in virus replication complexes (VRCs) of tobamovirus infected
CC cells. {ECO:0000250|UniProtKB:A0A0S4IJL0}.
CC -!- MISCELLANEOUS: The basic functional RuBisCO is composed of a large
CC chain homodimer in a 'head-to-tail' conformation. In form I RuBisCO
CC this homodimer is arranged in a barrel-like tetramer with the small
CC subunits forming a tetrameric 'cap' on each end of the 'barrel'.
CC {ECO:0000255|HAMAP-Rule:MF_00860}.
CC -!- SIMILARITY: Belongs to the RuBisCO small chain family.
CC {ECO:0000255|HAMAP-Rule:MF_00860}.
