Microvirin (MVN)---a lectin from Microcystis aeruginosa

Introduction

This plasmid is a basic part of the mannan binding lectin Microvirin (MVN). Microvirin can be expressed in E. coli and it can bind to Microcystis aeruginosa PCC7806 specifically.

Usage and Biology

MVN is a lectin isolated from the cyanobacteria Microcystis aeruginosa PCC7806. It is an 108 aa protein that consists of 2 domains. According to a carbohydrate microarray carried out previously, MVN binds to carbohydrate and the highest signals are observed with structures that contain α(1→2) linked mannose residues [1]. A binding partner of MVN was identified in the lipopolysaccharide (LPS) fraction of M. aeruginosa PCC7806 and it possibly represents the O-antigen of a LPS. MVN has been previously expressed in E. coli and its binding effect to cyanobacteria cells is species-specific [1].

Figure 2. Solution structure of MVN. MVN consists of 2 domains, domain A and domain B, which are colored yellow and blue respectively. Domain A is formed by residues 38-93 while domain B is formed by residues 1-37 and 94-108. The mannan binding site is only found in domain A. This figure is taken from Protein Data Bank (PDB ID: 2Y1S).
