چکیده

The Escherichia coli cell division gene ftsW (2 min) was cloned and sequenced. It encodes a hydrophobic protein(s) with 414 and/or 384 amino acid residues. The deduced amino acid sequence and the hydropathy profile of the protein showed high homology with those of the E. coli RodA protein functioning in determination of the cell shape and the Bacillus subtilis SpoVE protein functioning in spore formation. Probably similar functional membrane proteins are involved in these three cell cycle process.

Determinants for the subcellular localization and function of a nonessential SEDS protein.

The Bacillus subtilis SpoVE integral membrane protein is essential for the heat resistance of spores, probably because of its involvement in spore peptidoglycan synthesis. We found that an SpoVE-yellow fluorescent protein (YFP) fusion protein becomes localized to the forespore during the earliest stages of engulfment, and this pattern is maintained throughout sporulation. SpoVE belongs to a wel...

Interactions between late-acting proteins required for peptidoglycan synthesis during sporulation.

The requirement of peptidoglycan synthesis for growth complicates the analysis of interactions between proteins involved in this pathway. In particular, the latter steps that involve membrane-linked substrates have proven largely recalcitrant to in vivo analysis. Here, we have taken advantage of the peptidoglycan synthesis that occurs during sporulation in Bacillus subtilis to examine the inter...

Cooperative Recruitment of FtsW to the Division Site of Bacillus subtilis

Five essential proteins are known to assemble at the division site of Bacillus subtilis. However, the recruitment of the FtsW homolog is still unclear. Here, we take advantage of spore germination to facilitate the depletion of essential proteins and to study the divisome assembly in the absence of previous division events. We show that, unlike what has been shown for the Escherichia coli divis...

The division and cell wall gene cluster of Enterococcus hirae S185.

A chromosomal 10355-bp segment of Enterococcus hirae S185 contains nine orfs which occur in the same order as the MraW-, FtsL-, PBP3-, MraY-, MurD-, MurG-, FtsQ-, FtsA- and FtsZ-encoding genes of the division and cell wall clusters of Escherichia coli and Bacillus subtilis. The E. hirae DNA segment lacks the genes which in E. coli encode the ligases Ddl, MurC, MurE and MurF and the integral mem...

Artificial septal targeting of Bacillus subtilis cell division proteins in Escherichia coli: an interspecies approach to the study of protein-protein interactions in multiprotein complexes.

Bacterial cell division is mediated by a set of proteins that assemble to form a large multiprotein complex called the divisome. Recent studies in Bacillus subtilis and Escherichia coli indicate that cell division proteins are involved in multiple cooperative binding interactions, thus presenting a technical challenge to the analysis of these interactions. We report here the use of an E. coli a...
