InterPro domain: IPR019545

The DM13 domain has been identified in animal proteins containing a DOMONdomain likely to function as cytochromes involved in as yetunidentified redox reactions potentially related to protein hydroxylation oroxidative cross-linking. However, it is also found in bacteria. The DM13domain contains a nearly absolutely conserved cysteine, which can bepotentially involved in a redox reaction either as a nacked thiol group or bybinding a prosthetic group like heme [ 1 ].

The DM13 domain is predicted to have a beta-strand-rich fold [ 2 ].
