Which of the Following Proteins is Most Active in Divisome

Question

Which of the following proteins is most active in divisome complexes?
A) FtsZ
B) crescentin
C) MinCD
D) MreB

Accepted Answer

FtsZ is the bacterial homolog of tubulin and forms a ring-like structure at the site of cell division, where it recruits other proteins to form the divisome complex. FtsZ is considered to be the most active protein in divisome complexes as it plays a central role in initiating cell division and is required for the localization of other cell division proteins such as FtsA, FtsK, FtsQ, and FtsI. Crescentin is a cytoskeletal protein found in Caulobacter crescentus that is involved in cell shape and not cell division. MinCD is a pair of proteins that act as a negative regulatory system for cell division to prevent it from occurring at the wrong time or place. MreB is involved in cell shape determination and is not directly involved in cell division.
