General Information
| Biological Significance | Protein A is a 40-60 kDa MSCRAMM (microbial surface components recognizing adhesive matrix molecules) surface protein originally found in the cell wall of the bacteria Staphylococcus aureus. It is encoded by the spa gene and its regulation is controlled by DNA topology, cellular osmolarity, and a two-component system called ArlS-ArlR. It has found use in biochemical research because of its ability to bind immunoglobulins. It binds proteins from many of mammalian species, most notably IgGs. |
