Cell division apparatus

Question 7

What are the functions of the following 3 things during cell division?

FtsZ

ZipA

FtsA

Answer 7

• FtsZ: forms ring around center of cell; related to tubulin

• ZipA: anchor that connects FtsZ ring to cytoplasmic
membrane

• FtsA: helps connect FtsZ ring to membrane and also
recruits other divisome proteins
•Related to actin
