Characterization of these mutants allowed the identification of three separate FtsZ portions: the N‐terminal of about 150 amino acids the C‐terminal of about 60 amino acids, which corresponds to the less conserved portion of the protein and a central region of about 150 residues.
E coli pbp3 in vivo dimer series#
Using the same strategy, a series of 10 novel mutants of FtsZ that are unable to dimerize was selected, and a deletion analysis of the protein was carried out. coli (Weiss et al. PBP3 is mainly periplasmic, with a 23 residues cytoplasmic tail and a single transmembrane helix. coli and they have different cellular functions (Spratt, 1975): inactivation or depletion of PBP2 leads to spherical cells due to inhibition of cell elongation, whereas inactivation or depletion of PBP3 results in filamentous cells due to a block in new cell poles synthesis. In Escherichia coli, penicillin-binding protein 3 (PBP3), also known as FtsI, is a central component of the divisome, catalyzing cross-linking of the cell wall peptidoglycan during cell division. coli inner membrane, without concomitant. The fused protein resulted in a functional λ repressor and was able to complement the thermosensitive mutant ftsZ84. PBP3 is the monofunctional peptidoglycan transpeptidase (TPase) essential for cell division in E. Two of these, PBP2 and PBP3, are present in E. Our integrated in vivo and in vitro analysis provides evidence that MatP can interact with lipid membranes reproducing the phospholipid mixture in the E. cross-linking of the cell wall peptidoglycan during cell. A gene fusion comprising the N‐terminal end of the λcI repressor gene and the complete E. In Escherichia coli, penicillin-binding protein 3 (PBP3), also known as FtsI, is a central component of the divisome, catalyzing. Paolozzi, L.Ī hybrid assay, based on the properties of the λ repressor, was developed to detect FtsZ dimerization in Escherichia coli in vivo.
