(GenBank) Cell division GTPase (YP_062434.1| cell divison protein [Leifsonia xyli subsp. xyli str. CTCB07]; NP_787643.1| cell division protein FtsZ [Tropheryma whipplei str. Twist]). This protein is essential to the cell-division process. It 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. Binds to and hydrolyzes GTP (By similarity). pfam00091, Tubulin,Tubulin/FtsZ family, GTPase domain. pfam03953, Tubulin_C,Tubulin/FtsZ family, C-terminal domain. ftsZ: cell division protein FtsZ; High confidence in function and specificity
