Distribution of Subgroups of enzyme Chitinase involved in the 20 Vibrio species with complete genomes. Each of the columns corresponds to a chitinase cluster. The number within the box indicates the copy numbers of that gene cluster. Class I contains a family 18 chitinase domain; Class II contains a family 18 chitinase domain with a chitinase insertion domain; Class III contains a family 19 chitinase domain; Class IV contains no significant chitinase domain based on NCBI conserved domain database. Columns belonged to the same class indicate they share similar component patterns of structure domains but failed to be clustered into the same protein family
