Material
FtsZ is a bacterial cytoskeletal protein that is essential for cell division many prokaryotes (1).  It has been shown to be a bacterial homolog of eukaryotic tubulin, based both on a low sequence identity and a striking structural similarity (2).  Just like eukaryotic tubulin, FtsZ polymerizes as well as binds and hydrolyzes GTP in a polymerization dependent manner.

Streptococcus pneumoniae FtsZ protein has been purified after over-expression in E.coli.  S.p. FtsZ has a 6xHis tag and an approximate molecular weight of 45 kDa (Fig. 1).  FTZ03 is provided as a lyophilized protein with buffer and stabilizers.

Purity
Protein purity is determined by scanning densitometry of Coomassie Blue stained protein on a 10% polyacrylamide gel.  FtsZ protein was calculated to be >90% pure (see Figure 1, Lane 2).
