Sequence of ML5H8, a novel putative chitin-binding protein. An alignment of the ML5H8 protein with the sequences of chitin-binding domains of peritrophin-A type from molluscs and arthropods. Positions with < 80% and < 60% conservation are indicated in black and gray, respectively. Peritrophin-A is an extracellular domain that contains six conserved cysteines (indicated by #) that probably form three disulphide bridges. GenBank or Swiss-Prot numbers are indicated on the left.
