CC -!- FUNCTION: Exhibits GTPase activity which converts GTP ligands to GDP
CC (PubMed:29769312). Component of the plastid division machinery
CC consisting in a binary fission accomplished by the simultaneous
CC constriction of the FtsZ ring on the stromal side of the inner envelope
CC membrane, and the ARC5 ring on the cytosolic side of the outer envelope
CC membrane (PubMed:25731613). Required for plastid division in a dose-
CC dependent manner. In the vegetative shoot apex, at the shoot apical
CC meristem (SAM), where the proplastid-to-chloroplast transition takes
CC place, major contributor of plastid division in the L1 and L3 layers
CC and contributes equally with FTSZ1 in the L2 layer (PubMed:29920253).

CC -!- ACTIVITY REGULATION: GTPase activity is enhanced by ARC3.
CC {ECO:0000269|PubMed:29138260}.
CC -!- SUBUNIT: Aggregates to form a contractile ring-like structure;
CC contraction of the ring was accompanied by an increase in the filament
CC turnover rate (PubMed:29769312, PubMed:27322658). Self-interacts and
CC binds to FTSZ1 in heteromers to form two morphologically distinct types
CC of filaments, termed type-I (smooth filaments) and -II (rough
CC filaments), in a GTP-dependent manner; the GDP-induced disassembly is
CC inhibited by ARC6 (PubMed:29769312, PubMed:27322658). Interacts (via C-
CC terminus) with ARC6; this interaction enables ARC3 binding to FTSZ2
CC (PubMed:29967285, PubMed:29769312, PubMed:29138260). Part of a complex
CC made of ARC3, ARC6, FTSZ1 and FTSZ2 (PubMed:22823492). Binds to MCD1 in
CC an ARC6-dependent manner (PubMed:29967285). Binds to CDP1/PARC6
CC (PubMed:26527658, PubMed:28984364). Part of a complex made of
CC CDP1/PARC6, ARC3 and FtsZ proteins in the middle of the plastid; this
CC complex enhances the dynamics of Z rings during chloroplast division
CC (PubMed:30824505). Binds to PGK1 (PubMed:22823492).

CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast stroma
CC {ECO:0000269|PubMed:18431481, ECO:0000269|PubMed:22823492,
CC ECO:0000269|PubMed:29769312}. Plastid, chloroplast thylakoid membrane
CC {ECO:0000269|PubMed:18431481}; Peripheral membrane protein. Note=Forms
CC a contractile ring at the chloroplast midpoint that coaligns with FTSZ1
CC rings (PubMed:18431481, PubMed:29769312, PubMed:22823492,
CC PubMed:25731613). Exhibits a dynamic trunover in FtsZ ring facilitated
CC by ARC3-mediated destabilization (PubMed:25731613).
CC {ECO:0000269|PubMed:18431481, ECO:0000269|PubMed:22823492,
CC ECO:0000269|PubMed:25731613, ECO:0000269|PubMed:29769312}.
CC -!- INDUCTION: Slightly induced by gibberellic acid (GA).
CC {ECO:0000269|PubMed:23020316}.
CC -!- PTM: Filaments containing FTSZ2-1 are stabilized when in complex with
CC GTP but destabilized after conversion of GTP into GDP; ARC6 conteracts
CC this destabilisation by preventing the dissociation of GDP-bound FTSZ2
CC molecules thus inhibiting filament disassembly whereas ARC3 promotes
CC GTPase activity thus accelerating the conversion of GTP into GDP and
CC triggering FtsZ2 filaments disassembly. {ECO:0000269|PubMed:29138260,
CC ECO:0000269|PubMed:29769312}.
CC -!- PTM: Phosphorylation at Ser-143 is necessary for interactions with
CC ARC3, ARC6, FTSZ1 and FTSZ2-2. Phosphorylations at Ser-143 and Thr-286
CC are required for the formation of contractile ring at the chloroplast
CC midpoint. {ECO:0000269|PubMed:22823492}.
CC -!- DISRUPTION PHENOTYPE: Reduced number of heterogeneous large chloroplast
CC population (small and large plastids) due to impaired plastid division
CC (PubMed:25731613). Increased plastid volume in young leaf primordia and
CC in the shoot apical meristem (SAM), including the central zone as well
CC as peripheral zone of L1, the outermost layer, the peripheral zone of
CC L2, and the peripheral zone of L3 (PubMed:29920253).
CC {ECO:0000269|PubMed:18284374, ECO:0000269|PubMed:19995726,
CC ECO:0000269|PubMed:25731613, ECO:0000269|PubMed:29920253}.
CC -!- SIMILARITY: Belongs to the FtsZ family. {ECO:0000305}.
