Abstract:
To obtain iron from the host for growth, staphylococci have evolved sophisticated iron-scavenging systems including siderophores and a cell surface receptor for transferrin, the mammalian iron-transporting glycoprotein. The staphylococcal transferrin receptor has been identified as a member of a newly emerging family of multifunctional, cell-surface-associated glyceraldehyde-3-phosphate dehydrogenases, which not only retain their glycolytic enzyme activities but also bind diverse human serum proteins and possess NAD-ribosylating activity. These multiple functions suggest a potential contribution to virulence far beyond iron acquisition.

Sec61 protein conducting channel
In eukaryotes, the translocon complex comprises a core heterotrimeric translocator channel called the Sec61 complex. This channel includes three transmembrane proteins, Sec61α, Sec61β, and Sec61γ, and is the largest subunit of the translocon complex.
