The Curved-Rod Shape Typical of Caulobacter is Due to the Protein(s)

Question

The curved-rod shape typical of Caulobacter is due to the protein(s)
A) crescentin.
B) MreB.
C) crescentin and MreB.
D) neither crescentin nor MreB.

Accepted Answer

Crescentin and MreB are both involved in the formation of the curved-rod shape of Caulobacter. Crescentin is a protein that localizes to the poles of the cell and is required for the formation of the crescent-shaped cell body. MreB is a protein that forms a helical structure around the circumference of the cell and is required for the maintenance of cell shape.
