Iron uptake siderophores
WebHere we report that ARN family members facilitated the uptake of iron from the trihydroxamate siderophores ferrichrome, ferrichrome A, and triacetylfusarinine C. Uptake … WebFeb 27, 2014 · Siderophores are organic compounds with low molecular masses that are produced by microorganisms and plants growing under low iron conditions. The primary function of these compounds is to chelate the ferric iron [Fe (III)] from different terrestrial and aquatic habitats and thereby make it available for microbial and plant cells.
