Zusammenfassung:
Durch die Klonierung und rekombinante Expression verschiedener Pathogenitätsgene aus Shigella flexneri in Escherichia coli sowie die Aufreinigung der resultierenden Genprodukte konnten verschiedene biochemische Untersuchungen und Kristallisationsversuche an IpgA, IpgB, IpgC, IpgD, OSpD1, Spa15, IpaA, IpaB, IpaC und weitern durchgeführt werden.
Diese Produkte sind Teil des Typ III-Translokationssystems und wichtig für die Invasion von Shigella in die Epithelzellen des Darms.
