在从延伸到分隔的过渡过程中,大肠杆菌在未来的分裂位点建立了环状肽聚糖生长区。这种隔前肽聚糖合成不需要细胞分裂特异性肽聚糖转肽酶PBP 3或大多数其他细胞分裂蛋白,但它确实需要FtsZ、其膜锚定ZipA和至少一种双功能转糖基酶-转肽酶PBP 1A或PBP 1B。在这里,我们表明PBP 1A和PBP 1B与ZipA相互作用,并定位于PBP 3抑制的细胞中的隔前位点。ZipA刺激PBP 1A的糖基转移酶活性。膜锚定的细胞分裂蛋白FtsN定位于隔前位点,并刺激PBP 1B的两种活性。基因zipA和ftsN可以在ftsA* 突变细胞中单独缺失,但同时缺失这两种蛋白质是致命的,并且细胞不建立隔前位点。我们的数据支持一个模型,根据该模型,ZipA和FtsN-FtsA在连接细胞溶质FtsZ环与膜锚定的肽聚糖酶在隔前阶段的包膜生长具有半冗余的作用。蛋白质FtsZ、ZipA和PBP 1A或PBP 1B是在E.杆菌在这里,Pazos等人提供了ZipA和FtsA-FtsN将胞质FtsZ环与膜锚定的PBPs连接的证据。
During the transition from elongation to septation, Escherichia coli establishes a ring-like peptidoglycan growth zone at the future division site. This preseptal peptidoglycan synthesis does not require the cell division-specific peptidoglycan transpeptidase PBP3 or most of the other cell division proteins, but it does require FtsZ, its membrane-anchor ZipA and at least one of the bi-functional transglycosylase-transpeptidases, PBP1A or PBP1B. Here we show that PBP1A and PBP1B interact with ZipA and localise to preseptal sites in cells with inhibited PBP3. ZipA stimulates the glycosyltransferase activity of PBP1A. The membrane-anchored cell division protein FtsN localises at preseptal sites and stimulates both activities of PBP1B. Genes zipA and ftsN can be individually deleted in ftsA* mutant cells, but the simultaneous depletion of both proteins is lethal and cells do not establish preseptal sites. Our data support a model according to which ZipA and FtsN-FtsA have semi-redundant roles in connecting the cytosolic FtsZ ring with the membrane-anchored peptidoglycan synthases during the preseptal phase of envelope growth. Proteins FtsZ, ZipA, and either PBP1A or PBP1B are required for the synthesis of preseptal peptidoglycan at the future cell division site in E. coli. Here, Pazos et al. provide evidence that ZipA and FtsA-FtsN connect the cytosolic FtsZ ring with the membrane-anchored PBPs.
