title: PorA VR3 Typing Database: a web-based resource for the determination of PorA VR3 alleles of Neisseria meningitidis.
abstract: The variable regions (VR) of the surface-exposed PorA protein of Meningococci are used for subtyping and are considered the most abundant epitopes of outer membrane vesicle-based vaccine preparations. We have developed both a database that maintains all the known VR3 alleles and a web-based application for the rapid identification and submission of new VR3 variants based on sequence comparison.
