The gene ftsZ plays a central role in division.

Mutations in ftsZ block septum formation and generate filaments.

Overexpression induces minicells by causing an increased number of septation events per unit cell mass.

FtsZ (the protein) recruits a battery of cell division proteins that are responsible for synthesis of the new septum.

Cytokinin biosynthesis, catalyzed by isopentenyl transferase (IPT), is the addition of the isopentenyl side chain from DMAPP (dimethylallyl diphosphate) to an adenosine moiety (ATP or ADP). iPRTP or iPRDP is converted to ZTP or ZDP respectively by cytochrome P450 monooxygenase (CYP735A) and eventually is converted to zeatin.
