RT "Identification of a novel iron regulated staphylococcal surface protein
RT with haptoglobin-haemoglobin binding activity.";
RL Mol. Microbiol. 49:37-53(2003).
CC -!- FUNCTION: Binds human plasma haptoglobin-hemoglobin complexes,
CC haptoglobin and hemoglobin. Binds haptoglobin-hemoglobin complexes with
CC significantly higher affinity than haptoglobin alone.
CC {ECO:0000269|PubMed:12823809}.
CC -!- SUBCELLULAR LOCATION: Secreted, cell wall {ECO:0000305}; Peptidoglycan-
CC anchor {ECO:0000305}.
CC -!- INDUCTION: Expression was observed only in the late logarithmic and
CC stationary phase. Repressed by the ferric uptake repressor (fur)
CC protein in the presence of iron.
CC -!- DOMAIN: The NEAT 1 domain binds with higher affinity than the NEAT 2
CC domain haptoglobin-hemoglobin complexes, haptoglobin and hemoglobin.
CC {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the IsdH family. {ECO:0000305}.
