Structural highlights
FunctionPublication Abstract from PubMedA 1.1 A resolution, room-temperature X-ray structure and a 2.1 A resolution neutron structure of a chitin-degrading lytic polysaccharide monooxygenase domain from the bacterium Jonesia denitrificans (JdLPMO10A) show a putative dioxygen species equatorially bound to the active site copper. Both structures show an elongated density for the dioxygen, most consistent with a Cu(II)-bound peroxide. The coordination environment is consistent with Cu(II). In the neutron and X-ray structures, difference maps reveal the N-terminal amino group, involved in copper coordination, is present as a mixed ND2 and ND-, suggesting a role for the copper ion in shifting the pKa of the amino terminus.
