There is an N-terminal (Green) protease domain with a trypsin/chymotrypsin fold and also a C-terminal (Red) Ig fold. These different domains result in different stability and folds, as well as their ability to evolve and function. <scene name='79/799596/Spacefill/2'>VesB spacefill</scene> shows the shape and dimensions of the molecule, as well as the shapes of surface a conformer might present. There are both <scene name='79/799596/Hydrophobic/2'>hydrophilic and hydrophobic</scene> sections of VesB. Pink is polar, gray is hydrophobic, and red is oxygen. Its surface is closely split between hydrophilic and hydrophobic. The alpha helices make up the majority of the hydrophilic areas, showing areas where water would be attracted to VesB. The crystal structure of VesB was solved without a ligand, however, any protein containing RX (R is arginine, X is another amino acid) is a VesB ligand. His78, Asp125, and Ser221 make up the VesB <scene name='79/799596/Catalytic_triad/3'>catalytic triad</scene>. Aspartic acid is deprotonated and proton transfer moves from histidine to aspartic acid, meaning histidine is also deprotonated. Histidine then accepts a proton from serine's hydroxyl group, allowing serine to attack a substrate. This trio of amino acids work together to help VesB effectively cleave the substrate. Asp194 (Red) and Asp 220 (Black) coordinate the N terminus amino group in active VesB. Ile16 (Green) and Ile33 (Blue) occupies the hydrophobic pocket while Val159 (Yellow) and Val180 (Orange) assist in hydrogen bonding. These amino acids help form the <scene name='79/799596/Active_site/8'>active site</scene> of VesB. Leu158 (Brown) assists in cleaving the substrate. Tyr 250 (Purple) coordinates an Na+ ion that binds to and allosterically enhances thrombin activity. Proline residue near Lys224 (Pink) inhibits this Na+ ion binding. ==

	== VesB is uncompetitively inhibited by Boc-Gln-Ala-Arg-7-amino-4-AMC. This shows that this peptide does not have an impact on VesB function and that VesB is able to effectively cleave substrate. ==		== VesB is uncompetitively inhibited by Boc-Gln-Ala-Arg-7-amino-4-AMC.

	== By studying VesB, improved treatment and prevention of cholera could be discovered. While it is not a major problem in the United States, lives could be improved and saved in areas such such as Africa, where cholera is more prevalent. This would allow more social interaction without concern of disease, which would be beneficial as many people are in close contact in these areas of contamination. ==		== By studying VesB, improved treatment and prevention of cholera could be discovered.
