virulence-conferring siderophore petrobactin in Bacillus anthracis, is shown to catalyze efficient ATP-dependent condensation of spermidine, but not N1-(3,4-dihydroxbenzoyl)-spermidine, with N8-citryl-spermidine or N1-(3,4-dihydroxbenzoyl)-N8-citryl-spermidine, suggesting that N1-(3,4-dihydroxbenzoyl)-spermidine is very unlikely to be a significant intermediate in petrobactin biosynthesis, contrary to previous
AsbB 酶参与炭疽芽孢杆菌中赋予毒力的铁载体岩杆菌素的生物合成,显示可催化亚精胺与 N8- citryl-spermidine 或 N1-(3,4-dihydroxybenzoyl)-N8-citryl-spermidine,表明 N1-(3,4-dihydroxybenzoyl)-spermidine 不太可能是 petrobactin 生物合成中的重要中间体,这与之前的建议相反。
