Structural highlights
FunctionSIAT1_HAEIN Part of the tripartite ATP-independent periplasmic (TRAP) transport system SiaPT involved in the uptake of sialic acid (N-acetyl-beta-neuraminate). N-Acetylneuraminate can then be incorporated into the lipopolysaccharides as a terminal non-reducing sugar, protecting the bacterium from complement-mediated killing by normal human serum.[1] References
