Homology model depicting the overlapping catalytic sites of PfCHT1,
PgCHT1, and human chitotriosidase complexed with allosamidin (yellow,
PfCHT1; blue, PgCHT1; white, human chitotriosidase). The three active
sites are almost perfectly superimposable, with the exception of a
novel pocket found in PgCHT1, seen at lower right. The models were
built by using the structure of hevamine complexed with allosamidin as
a template.
