FTSZ1 | Cell division protein FtsZ homolog 1, chloroplastic; Exhibits GTPase activity. Component of the plastid division machinery that forms a contractile ring at the division site. Required for plastid division in a dose-dependent manner. Involved in blue light-induced chloroplast movements. May regulate thylakoid development. Belongs to the FtsZ family. (433 aa) | ||||
ARC3 | Protein ACCUMULATION AND REPLICATION OF CHLOROPLASTS 3; Z-ring accessory protein involved in the initiation of plastid division and division site placement (might functionally replace bacterial MinC). May control the rate of chloroplast expansion. Seems to influence stromule (stroma-filled tubular extensions of the plastid envelope membrane) length and frequency. (741 aa) | ||||
PDV2 | Plastid division protein PDV2; Component of the plastid division machinery. Required to mediate the recruitment of ARC5 at the midplastid constriction site in the cytoplasm. Relays plastid division site position between stroma and outer surface via interactions with the cytoplasmic ARC5 and the inner membrane ARC6 that recruits stromal FtsZ ring. (307 aa) |
