| Sumario: | Streptococcus pneumoniae is a human pathogen bacterium capable of using hemoglobin (Hb) and haem as a single iron source but not in presence of lactoferrin. This bacterium has developed a mechanism through the expression of several membrane proteins that bind to iron sources, between them a lipoprotein of 37 kDa called Spbhp-37 (Streptococcus pneumoniae haem-binding protein) involved in iron acquisition. The Spbhp-37 role is to maintain the viability of S. pneumoniae in presence of Hb or haem. This mechanism is relevant during the invasion of S. pneumoniae to human tissue for the acquisition of iron from hemoglobin or haem as an iron source. |
