枯草芽孢杆菌的comQXPA基因座编码典型的革兰氏阳性细菌的群体感应(QS)系统。它编码四种蛋白质,ComQ异戊二烯基转移酶,ComX前肽信号,ComP组氨酸激酶和ComA反应调节剂。它们由位于同一条染色体上的四个相邻基因编码。在这里,我们提出了一个全面的普查结果comQXPA样基因排列在2620个完整的和6970个草案原核基因组(测序到2013年底)。在手动检查数据的假阳性和假阴性命中后,我们发现了39个新的类似com的预测。普查数据显示,除了B。枯草芽孢杆菌和近亲属,20个comQXPA样基因座预测出现在B之外。枯草分支其中包括梭菌目的一些物种,但没有硬壁菌门以外的物种。在comQXPA基因座中观察到特征性的基因重叠模式,这与B不同。枯草杆菌样和非B.类似枯草杆菌的分支。与B中的ComX肽相关的显著序列变异性。subtilis进化枝在非B. subtilis进化枝,表明在底层群体感应系统中存在非常相似的进化约束。
The comQXPA locus of Bacillus subtilis encodes a quorum sensing (QS) system typical of Gram positive bacteria. It encodes four proteins, the ComQ isoprenyl transferase, the ComX pre-peptide signal, the ComP histidine kinase, and the ComA response regulator. These are encoded by four adjacent genes all situated on the same chromosome strand. Here we present results of a comprehensive census of comQXPA-like gene arrangements in 2620 complete and 6970 draft prokaryotic genomes (sequenced by the end of 2013). After manually checking the data for false-positive and false-negative hits, we found 39 novel com-like predictions. The census data show that in addition to B. subtilis and close relatives, 20 comQXPA-like loci are predicted to occur outside the B. subtilis clade. These include some species of Clostridiales order, but none outside the phylum Firmicutes. Characteristic gene-overlap patterns were observed in comQXPA loci, which were different for the B. subtilis-like and non-B. subtilis-like clades. Pronounced sequence variability associated with the ComX peptide in B. subtilis clade is evident also in the non-B. subtilis clade suggesting grossly similar evolutionary constraints in the underlying quorum sensing systems.
