The primary role of bacterial periplasmic binding proteins is sequestration of essential metabolites present at a low concentration in the periplasm and making them available for active transporters that transfer these ligands into the bacterial cell. The periplasmic binding proteins(SiaP) from the tripartite ATP-independent periplasmic (TRAP) transport system that transports mammalian host-derived sialic acids, have been well studied from different pathogenic bacteria, including , , , and SiaPs bind the sialic acid N-acetylneuraminic acid (Neu5Ac) with nanomolar affinity by forming electrostatic and hydrogen bonding interactions.

Muscovy duck parvovirus (MDPV) and goose parvovirus (GPV) have both been found to cause high mortality and morbidity in Muscovy ducklings. Specific detection is often rife with false positives due to high identity at the genomic nucleotide level and antigenic similarity between MDPVs and GPVs. In this study, significantly variable regions were found, via non-structural (NS) comparison, between MDPV and GPV NS genes; however, NS genes were conserved within the MDPV and GPV groups. Read More
