Domain of unknown function (DUF3472). This presumed domain is functionally uncharacterized. This domain is found in bacteria, eukaryotes and viruses. This domain is typically between 174 to 190 amino acids in length. This domain has a single completely conserved residue G that may be functionally important.

Putative mucin or carbohydrate-binding module. This family is the putative binding domain for the substrates of enhancin, and other similar metallopeptidases. This is not the enzymically active, peptidase, part of the proteins - see pfam13402.

Chitin-binding domain of chitinase C. Chitin-binding domain of chitinase C (ChiC) of Streptomyces griseus and related proteins. Chitinase C is a family 19 chitinase, and consists of a N-terminal chitin binding domain and a C-terminal chitin-catalytic domain that effects degradation. Chitinases function in invertebrates in the degradation of old exoskeletons, in fungi to utilize chitin in cell walls, and in bacteria which use chitin as an energy source. ChiC contains the characteristic chitin-binding aromatic residues.

Chitin-binding domain type 3.
