(21, 24) During the sequencing of the genome, comparative genome analysis identified five novel genes, including FtsZ, dynamin, and Mda1 (mitochondrial division apparatus 1) gene, which are related to mt- and pt-division machineries.
FtsZ1 did not form ring structures at the division site, and Mda1, which is part of the outer membrane mt-division machinery, was not recognized in ZED-downregulated cells.
Finally, the outer membrane mt-division machinery is composed of the Mda1 ring, the outer MD ring, the dynamin ring, and unknown rings.
