The Hb-interacting domain (HID) is found duplicated in Heme-binding protein Shr from Streptococcus pyogenes, a potentially lethal human pathogen, and in one to six copies in other uncharacterised bacterial proteins. Shr is a virulence factor that captures Hb and binds to the oxidized form of heme through an N-terminal region that contains two copies of this domain. HID shows a beta-sandwich-type fold in which two antiparallel beta-sheets are flanked by an alpha-helix [1].	Domain
