Human serum albumin (HSA) is the major protein in blood plasma and is responsible for circulatory transport of a range of small molecules including fatty acids, metal ions and drugs. We previously identified the major plasma Zn2+ transport site on HSA and revealed that fatty-acid binding (at a distinct site called the FA2 site) and Zn2+ binding are interdependent via an allosteric mechanism. Since binding affinities o Read More

Among the human copper-containing monooxygenases, Tyrosinase (Ty) is an important enzyme involved in the determinant step of the biosynthetic pathway of melanin pigment. In this pathway, Ty catalyzes the tyrosine monooxygenation into L-DOPA-quinone, which is the precursor of the skin pigment melanin. Ty inhibitors/activators are a well-established approach for controlling in vivo melanin production, so their developmen Read More

Malaria is one of the world’s most devastating diseases, particularly in the tropics. In humans, Plasmodium falciparum lives mainly within red blood cells, and malaria pathogenesis depends on the red blood cells being infected with the parasite. Nonesterified fatty acids (NEFAs), including cis-9-octadecenoic acid, and phospholipids have been critical for complete parasite growth in serum-free culture, although the efficacy of NE Read More

Pathological aggregation of endogenous proteins is a common feature of many neurodegenerative diseases. This is generally accompanied by elevated levels of oxidative stress associated with transition metal dyshomeostasis. As such, strategies targeted toward rectifying metal imbalance are increasingly becoming an attractive therapeutic option. One class of compound showing such therapeutic potential are the bis(thios Read More

Noble metal nanomaterials, such as gold or silver nanoparticles, exhibit unique photonic, electronic, catalytic and therapeutic properties. The high versatility in their synthesis, especially size and shape features, as well as in the surface functionalization by, e.g., physisorption, direct chemisorption of thiol derivatives and covalent binding through bifunctional linkers or specific affinity interactions, prompted their wides Read More

The description of the cell life needs not only the knowledge of its genome and proteome, but also of the location of the metal ions and their different complex species in the subcellular compartments, that is of metallome. The cross-talk among these players of the omics’ world secures the cellular homeostasis by means of a complex network, the alteration of which may give rise to many diseases. Copper and zinc ions l Read More
