dc.description.abstract The physico-chemical properties of coniferyl alcohol oxidase (CAO), a copper containing glycoprotein spatiotemporally associated with lignification in conifers, is reported here. By electron paramagnetic resonance spectroscopy, only type 3 copper was indicated in CAO. CAO oxidizes several laccase substrates; however, it is not a blue-copper protein and monoclonal antibodies against both native and deglycosylated CAO did not recognize any of several laccases. The N-terminal sequence of CAO, H2N-X E L A Y S P P Y X P S, was non-homologous with known enzymes. Transparent copper, tetrameric structure, aminoacid composition, phenylhydrazine and tropolone inhibition, and SDS enhancement of CAO activity indicate that CAO is an o-diphenol oxidase. en_US
