laccase activity is positively correlated to the growth of the fungus. Four laccase isoforms are secreted by the fungus, and tentatively named LI1, LI2, LI3 and LI4. LI2, LI3 and LI4 are produced during the stationary phase (between 408 and 456 h approximately) while LI1 is produced during the lag, exponential and stationary phases of growth. Maximal laccase activity is observed at the beginning of the stationary phase

needle-shaped crystals of sPOXA3b (the small subunit of laccase) grew in a few days at 21 °C using the sitting-drop vapour-diffusion method to approximate dimensions of 0.1 * 0.1 * 0.3 mm. The crystals belong to the primitive tetragonal space group P4(1)2(1)2 or P4(3)2(1)2, with unit-cell parameters a = 126.6, c = 53.9 A

site-directed mutagenesis, the mutation in a highly conserved region perturbs the structural local environment in POXA1b, leading to a large rearrangement of the enzyme structure. The mutant shows highly reduced activity compared to the wild-type enzyme and is inactive with substrate syringaldazine
additional information
deletion of the C-terminal extension of 4 or 16 amino acids leads to truncated mutants which lose the high stability at pH 10, while they show an increased stability at pH 5.0, the thermostability is unaltered compared to the wild-type enzyme
