method X-Ray Diffractionresolution 2.8 Å
domain Consists of two globular domains with a connecting core helix.
similarity Belongs to the ftsz family.[tubulin]
subunit Aggregate to form a ring-like structure (by similarity).
genes FTSZ1, MJ0370 (M. jannaschii)
function This protein is essential to the cell-division process. Binds to and hydrolyzes gtp (by similarity). Its seems to assemble into a dynamic ring on the inner surface of the cytoplasmic membrane at the place where division will occur, and the formation of the ring is the signal for septation to begin.
