Modern life requires many different metal ions, which enable diverse biochemical functions. It is commonly assumed that ions’ environmental availabilities controlled the evolution of early life. We argue can only explore chemistry encounters, and fortuitous chemical interactions between ions biological compounds be selected for if they first occur sufficiently frequently. calculated maximal transition ion concentrations in ancient ocean, determining amounts biologically important were orders magnitude lower than ferrous iron. Under such conditions, primitive bioligands would predominantly interact with Fe(II). While other metals certain environments may have provided evolutionary opportunities, capacities Fe(II), Fe–S clusters, or plentiful magnesium calcium could satisfied all functions needed by Primitive organisms used Fe(II) exclusively their requirements.

Metalloproteins play a fundamental role in molecular biology, contributing to various biological processes. However, the discovery of high-affinity ligands targeting metalloproteins has been delayed due, part, lack suitable tools and data. Molecular docking, widely used technique for virtual screening small-molecule ligand interactions with proteins, often faces challenges when applied due particular nature metal bond. To address these limitations associated docking metalloproteins, we introduce knowledge-driven approach known as "metalloprotein bias docking" (MBD), which extends AutoDock Bias technique. We assembled comprehensive data set metalloprotein-ligand complexes from 15 different metalloprotein families, encompassing Ca, Co, Fe, Mg, Mn, Zn ions. Subsequently, conducted performance analysis our MBD method compared it conventional (CD) program AutoDock4, targets within set. Our results demonstrate that outperforms CD, significantly enhancing accuracy, selectivity, precision pose prediction. Additionally, observed positive correlation between predicted free energies corresponding experimental values. These findings underscore potential valuable tool effective exploration interactions.
