The crystal structure of transferrin binding protein A (TbpA) from Neisseria meningitidis serogroup B in complex with the C-lobe of human transferrin
Template:ABSTRACT PUBMED 22327295
Disease
[TRFE_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]
Function
[TRFE_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.
About this Structure
3v89 is a 2 chain structure with sequence from Homo sapiens and Neisseria meningitidis serogroup b. Full crystallographic information is available from OCA.
