The Nitrosopumilus maritimus CdvB, but Not FtsZ, Assembles into Polymers

Table 1

Summary on the domain analysis of the Nmar_0816 (1–216 aa) protein for its polymerization activity in yeast.

	Polymerization activity
Nmar_0816(1--216)	Yes
Nmar_0816(1--108)	No
Nmar_0816(109--216)	No
Nmar_0816(1--192)	Yes
Nmar_0816C123A	Yes

In Nmar_0816_(1--108) and Nmar_0816_(109--216), the core domain (1–181 aa) was disrupted. In Nmar_0816_C123A, the cysteine residue was mutated to alanine. In Nmar_0816_(1--192), the putative MIM2 motif was removed.
