Abstract
This study presents a combined method to analyze extracellular fungal laccases using a new anti-laccase antibody together with the identification of tryptic laccase peptides by mass spectrometry (nanoLC-ESI-MS/MS). The polyclonal anti-laccase antibody LccCbr2 was raised against peptides designed from the copper binding region 11 of fungal laccases using in silico data obtained from GenBank database. As a consequence, detection requires denaturation of the enzymes due to the stable conformation of the copper binding region II. The specificity of the antibody was shown with denatured laccase Lcc1 of Coprinopsis cinerea and laccase of Hypholoma fasciculare. LccCbr2 detected amounts as low as 5 ng of highly purified laccase, indicating a possible use of the antibody for quantification of laccase proteins. Denatured extracellular laccases from culture supernatants of the basidiomycetes C. cinerea, H. fasciculare, Lentinula edodes, Mycena sp., Piriformospora indica, Pleurotus cornucopiae, Pleurotus ostreatus, Pycnoporus cinnabarinus, Trametes versicolor and furthermore the ascomycete Verpa conica were detected with apparent molecular masses between 60 and 70 kDa by LccCbr2. The identity of extracellular laccases from C cinerea, H. fasciculare, P ostreatus, P. cinnabarinus and T versicolor were verified by tryptic peptides using nanoLC-ESI-MS/MS.
