Conserved Site

Copper type II, ascorbate-dependent monooxygenase, histidine-cluster-2 conserved site (IPR014783)

Short name: Cu2_ascorb_mOase_CS-2


Copper type II, ascorbate-dependent monooxygenases [PMID: 2792366] are a class of enzymes that requires copper as a cofactor and which uses ascorbate as an electron donor. This family contains two related enzymes, dopamine-beta-monooxygenase (EC: and peptidyl-glycine alpha-amidating monooxygenase (EC: There are a few regions of sequence similarities between these two enzymes, two of these regions contain clusters of conserved histidine residues which are most probably involved in binding copper.

This entry represents a conserved site that covers the second cluster of conserved histidine residues.
