Promotes bacterial attachment to both soluble and immobilized forms of fibrinogen in a dose-dependent manner. This binding occurs through the beta-chain of human fibrinogen. Could contribute to the initiation of foreign-body infection by allowing bacteria to adhere to biomaterial surfaces that have become coated with host proteins after implantation. Is important in the pathogenesis of central venous catheter (CVC)-associated infection model. The addition of calcium stimulates the interaction between fbe and fibrinogen, but this effect could be due to calcium binding to fibrinogen rather than to fbe. Belongs to the serine-aspartate repeat-containing protein (SDr) family.
