Common Namestaphylopine
DescriptionStaphylopine is a nicotianamine-like metallophore belonging to the class of small molecule metabolites. Its chemical structure features a complex arrangement that facilitates the chelation of transition metals, specifically cobalt and nickel, which are critical for bacterial survival and virulence. Staphylopine is synthesized and transported via the cobalt and nickel transporter (Cnt) system, which is essential for metal acquisition in Gram-positive bacteria, including the human pathogen Staphylococcus aureus (PMID:39442338 ). The biosynthesis of staphylopine involves key enzymes such as the aminobutanoyltransferase CntL and the cofactor-independent histidine racemase CntK (PMID:39424140 ). Staphylopine participates in various metabolic pathways, including the production of polyamines and siderophores, and its activity is regulated by metal sequestration-associated genes (cntA, cntK, cntL, and cntM), which are upregulated in clinical settings compared to laboratory conditions (PMID:38579524 ). Additionally, staphylopine's ability to sequester metals has implications for host-pathogen interactions, as it can be exploited by the host to intoxicate S. aureus (PMID:37737591 ), highlighting its role in the broader context of bacterial metal homeostasis and virulence strategies.
