LITERATURE
Cu2+
enzyme-bound, is eliminated by denaturation of the enzyme protein
Fe3+
non-heme iron, required. The catalytic non-heme iron, deeply buried in the CspLOX2 active site, is coordinated by three invariant histidines (His257, His262, His449), Asn453 and the carboxy group of the C-terminal Ile569. The sixth ligand of the octahedrally coordinated iron, which is positioned towards the putative substrate binding channel, is a water (Fe2+-H2O) or hydroxide molecule (Fe3+-OH) acting as a catalytic base for hydrogen abstraction during catalysis, coordination of the iron cofactor, overview
Manganese
-
mononuclear Mn center, 0.94 mol Mn per mol of protein
Mg2+
-
activation less effective than with Ca2+ in phosphate buffer
