Human serum trnasferrin bound to a fluorescent probe
Structural highlights
DiseaseTRFE_HUMAN Defects in TF are the cause of atransferrinemia (ATRAF) [MIM:209300. Atransferrinemia is rare autosomal recessive disorder characterized by iron overload and hypochromic anemia.[1] [2] FunctionTRFE_HUMAN Transferrins are iron binding transport proteins which can bind two Fe(3+) ions in association with the binding of an anion, usually bicarbonate. It is responsible for the transport of iron from sites of absorption and heme degradation to those of storage and utilization. Serum transferrin may also have a further role in stimulating cell proliferation. Publication Abstract from PubMedPorphyromonas gingivalis is a key oral anaerobic bacterium involved in human periodontitis, which may affect up to 15% adults worldwide. Using the membrane permeable fluorescent probe Fe-TRACER, we identified 17 iron-associated proteins in Porphyromonas gingivalis. We demonstrated the specific binding of the probe towards iron-associated proteins using transferrin as an example and provided an X-ray structure of the fluorescent probe-bound transferrin. Our study provides a basis for the understanding of iron homeostasis in pathogens, and our approach based on the integration of fluorescence imaging with proteomics and bioinformatics can be readily extended to mine other metalloproteomes in microbials.
