The mechanism of iron-compensation for manganese deficiency of Streptococcus pneumoniae.

Unlabelled: Given their involvement in catalysis, infection, and biofilm formation, Fe and Mn are essential for bacterial survival and virulence. In this study, we found that Streptococcus pneumoniae (S. pneumoniae) could grow in the Mn-deficient medium (MDCM).

Evolution and molecular mechanism of PitAs in iron transport of Streptococcus species.

Iron is an essential element for almost all bacteria. The iron ATP-binding cassette (ABC) transporters located on the cell membrane affects bacterial virulence and infection. Although a variety of Fe-transporters have been found in bacteria, their evolutionary processes are rarely studied.
