MCB 3020C Chapter Notes - Chapter 5: Ftsz, Mreb, Penicillin Binding Proteins
Document Summary
And control: bacterial cell division, 5. 1 binary fission. Growth: an increase in the number of cells: coli growth, cells elongate 2x their size and form a partition that constricts the cell into 2 daughter cells (binary fission) Septum: partition in cells during binary fission; results fro inward growth of the cytoplasmic membrane and cell wall from opposing directions: bacillus subtilis: septum forms without cell wall constrition, caulobacter: constriction occurs but no septum is formed. Generation: one when one cell eventually separates into 2 cell. Ftsa: related to actin (cytoskeletal protein in eukaryotes) ; helps connect ftsz ring to cytoplasmic membrane and get other proteins. 2: cell shape and mreb, mreb: protein that determines shape in bacteria; recruits other proteins that function in cell wall growth to make a specific pattern; coccoid bacteria lacks. Ftsz structurally related to tubulin: tubulin forms microtubules; important in mitosis and other processes.
