Sequence alignment of VerFtsZ of Verrucomicrobium spinosum with reference amino acid sequences of FtsZ from representative Bacteria with highlight of residues based on an identity threshold of at least 50% across taxa. The first and last block of the alignment shows the N-terminal and C-terminal region respectively while the middle four blocks form the core region (the first 70 poorly alignable residues of the N-terminal region are not shown). Identities are denoted with a '*' below the amino acid position. Red arrows indicate amino acid positions at which the sequence of Verrucomicrobium spinosum differs from the FtsZ sequences of all other Bacterial phyla in the alignment. The blue arrow indicates the position of uncommon Serine within the tubulin signature motif. L.lactis, Lactococcus lactis; N.gonorrhoeae, Neisseria gonorrhoeae; B. fragilis, Bacteroides fragilis; P. albensis, Prevotella albensis; N. punctiformae, Nostoc punctiformae; G. violaceus, Gloeobacter violaceus; B. cereus, Bacillus cereus; E. coli, Escherichia coli; T. pallidum, Treponema pallidum; L. interrogans, Leptospira interrogans; T. maritima, Thermotoga maritima; A. aeolicus, Aquifex aeolicus; VerFtsZ, Verrucomicrobium spinosum.
