Staphylococcus Aureus SuhB Protein (SaSuhB)

SaSuhB is a protein native to Staphylococcus aureus. While it is characterized as an inositol monophosphatase enzyme, it is also necessary for unimpaired pia-independent biofilm formation in S. aureus [1]. Moreover, further study of this protein has revealed that it is capable of forming macroscopic amyloid fibers when expressed in E. coli [2]. The fibers were characterized as being incredibly sticky, causing the researchers great trouble in trying to wash the fibers off of glass and plastic ware [2]. Additionally, SEM imagery revealed that bacteria were readily adhered to these fibers [2]. This combination of traits makes SaSuhB appear perfect for our application of forming strong, robust biofilms.
