A Bacillus subtilis gene termed yhfR encodes the only B. subtilis protein with significant sequence similarity to 2, 3-diphosphoglycerate-dependent phosphoglycerate mutases (dPGM). This gene is expressed at a low level during growth and sporulation, but deletion of yhfR had no effect on growth, sporulation, or spore germination and outgrowth. YhfR was expressed in and partially purified from Escherichia coli but had little if any PGM activity and gave no detectable PGM activity in B. subtilis. These data indicate that B. subtilis does not require YhfR and most likely does not require a dPGM.
一个名为yhfR的枯草芽孢杆菌基因编码了枯草芽孢杆菌中唯一一种与2,3-二磷酸甘油酸依赖性磷酸甘油酸变位酶(dPGM)具有显著序列相似性的蛋白质。该基因在生长和芽孢形成过程中低水平表达,但缺失yhfR对生长、芽孢形成或孢子萌发及生长没有影响。YhfR在大肠杆菌中表达并部分纯化,但几乎没有PGM活性,在枯草芽孢杆菌中也未检测到PGM活性。这些数据表明枯草芽孢杆菌不需要YhfR,很可能也不需要dPGM。
