Substrate specificities

Before the proteins belonging to AA10 were shown to be enzymes, they were known as chitin binding proteins (CBPs), since most characterized proteins had been identified in chitinolytic systems such as that of Serratia marcescens (REF), several Streptomyces species (REFs), ......, and show no other obvious function than just binding the substrate. Thus there exists several papers that have analyzed the binding preferences of AA10s.

Please see these references for an essential introduction to the CAZy classification system: [1, 2].
