Tubulin-like protein TubZ

UniProtKB accession:  Q74P24

Grouped By:  Matching UniProtKB accession

UniProtKB description:  A tubulin-like, filament forming GTPase; the motor component of the type III plasmid partition system which ensures correct segregation of the pBc10987 plasmid (Probable). Binds GTP and forms filaments (PubMed:22847006). The filaments seed from a DNA centromere-like site (tubC)-TubR complex which extends to surround the TubZ filaments. Highly dynamic filaments grow at the plus end and depolymerize at the minus end, a process called treadmilling. TubR-tubC complexes track the depolymerizing minus end of the filament, probably pulling plasmid within the cell (By similarity).
