Nice catch! The immobilization of a synthetic petrobactin derivative on agarose was crucial for the isolation and identification of a bacterial siderophore import protein for the first time from crude cell extracts. The biochemical and genetic characterization of the identified protein confirmed that FpiA (YclQ) is the principal petrobactin importer in Bacillus subtilis.
好赶上!合成石蜡蛋白衍生物在琼脂糖上的固定对于首次从粗细胞提取物中分离和鉴定细菌铁载体导入蛋白至关重要。鉴定出的蛋白质的生化和遗传学特征证实,FpiA(YclQ)是枯草芽孢杆菌中主要的岩石活化素进口商。
