根癌农杆菌具有两种多磷酸(polyP)激酶,其中一种(PPK1AT)负责形成polyP颗粒,而另一种(PPK2AT)用于通过使用polyP作为磷酸供体来磷酸化核苷二磷酸来补充NTP池。eYFP与PPK2 AT或来自真养罗尔斯通氏菌的聚P颗粒相关的磷酸酶PptA的融合物总是与A中的聚P颗粒共定位。tumefaciens,并允许在延时显微镜实验中跟踪polyP颗粒,而不需要用有毒染料DAPI标记细胞。PPK1AT与mCherry的融合形成了荧光信号,其通常附着于野生型细胞中的聚P颗粒,但不完全与之共定位。延时显微镜显示,大约三分之一的细胞群中的聚P颗粒在细胞分裂前不久或期间从旧极迁移到新极。许多细胞从头形成了第二个(nonmigrating)聚P颗粒在相反的细胞极细胞分裂完成之前,导致在两个女儿的细胞,每个有一个聚P颗粒在旧极后,隔膜形成。在丝裂霉素C处理或PopZ耗尽的细胞中,聚P颗粒的迁移是无序的,这表明聚P颗粒可以与DNA或在细胞周期中分离的其他分子相关联。
Agrobacterium tumefaciens has two polyphosphate (polyP) kinases, one of which (PPK1 AT) is responsible for the formation of polyP granules, while the other (PPK2 AT) is used for replenishing the NTP pools by using polyP as a phosphate donor to phosphorylate nucleoside diphosphates. Fusions of eYFP with PPK2 AT or of the polyP granule-associated phosin PptA from Ralstonia eutropha always co-localized with polyP granules in A. tumefaciens and allowed the tracking of polyP granules in time-lapse microscopy experiments without the necessity to label the cells with the toxic dye DAPI. Fusions of PPK1 AT with mCherry formed fluorescent signals often attached to, but not completely co-localizing with, polyP granules in wild-type cells. Time-lapse microscopy revealed that polyP granules in about one-third of a cell population migrated from the old pole to the new cell pole shortly before or during cell division. Many cells de novo formed a second (nonmigrating) polyP granule at the opposite cell pole before cell division was completed, resulting in two daughter cells each having a polyP granule at the old pole after septum formation. Migration of polyP granules was disordered in mitomycin C-treated or in PopZ-depleted cells, suggesting that polyP granules can associate with DNA or with other molecules that are segregated during the cell cycle.
