the enzyme laccase catalyses the formation of melanin by oxidizing L-DOPA, initiating a series of presumably spontaneous reactions that ultimately leads to the polymerization of the pigment in the yeast cell wall. There, melanin protects the cell from a multitude of environmental and host assaults. Kinetics of dopachrome formation are similar for L- and D-DOPA |
| 1.10.3.2 | melanin + O2 |
the enzyme decolorizes fungal melanin from Alternaria alternata strain NBCR 31805 or black hyphae of Cladosporium sp. strain B-1, but not synthetic melanin, overview |
| 1.10.3.2 | more |
involved in decomposition of lignin, discussion of physiological role |
| 1.10.3.2 | more |
involved in production of oxygen free radicals |
| 1.10.3.2 | more |
involved in melanin synthesis |
| 1.10.3.2 | more |
laccase couples catalytic oxidation of lignin with the four electron reduction of oxygen, the final product is water without any harmful intermediate making laccase the best candidate for the environmentally benign bleaching process |
| 1.10.3.2 | more |
the enzyme is involved in bioremdiation |
| 1.10.3.2 | more |
the laccase exhibits an inhibitory activity toward HIV-1 reverse transcriptase with an IC50 of 0.0022 mM |
| 1.10.3.2 | more |
laccases are able to oxidize a variety of substrates, ranging from mono- and polyphenols over aminophenols, methoxyphenols and aromatic amines to polycyclic aromatic hydrocarbons and certain lignin moieties |
