ANISERP: a new serpin from the parasite Anisakis simplex.

ABSTRACT:

Background

Serine proteinase inhibitors (serpins) finely regulate serine proteinase activity via a suicide substrate-like inhibitory mechanism. In parasitic nematodes, some serpins interact with host physiological processes; however, little is known about these essential molecules in Anisakis. This article reports the gene sequencing, cloning, expression and preliminary biochemical and bioinformatically-based structural characterization of a new Anisakis serpin (ANISERP).

Methods

The full AniSerp gene was cloned by specific RACE-PCR after screening an Anisakis simplex (L3) cDNA library. For biochemical assays, the AniSerp gene was subcloned into both prokaryotic and eukaryotic vectors, and the recombinant proteins were purified. The inhibitory properties of the proteins were
