过渡金属在生物系统中占有重要地位。它们的静电特性稳定酶活性位点的底物或反应中间体,而它们的高反应性则用于催化。然而,后一种性质使过渡金属在高浓度下具有毒性。像所有生物一样,细菌必须调节这些元素的水平,以满足其生理需求,同时避免伤害。因此,宿主利用过渡金属的重要性和毒性来防御细菌入侵者也就不足为奇了。这篇综述将讨论建立和新兴的模式在病原体-宿主界面的营养金属稳态。
Transition metals occupy an essential niche in biological systems. Their electrostatic properties stabilize substrates or reaction intermediates in the active sites of enzymes, while their heightened reactivity is harnessed for catalysis. However, the latter property renders transition metals toxic at high concentrations. Bacteria, like all living organisms, must regulate the levels of these elements to satisfy their physiological needs while avoiding harm. It is therefore not surprising that the host capitalizes on both the essentiality and toxicity of transition metals to defend against bacterial invaders. This review will discuss established and emerging paradigms in nutrient metal homeostasis at the pathogen-host interface.
