The enzymatic char.cter.s.ics.Km, kcat, pH and temper.tur. optima of the pur.fied laccas. have been deter.ined us.ng 2, 6-dimethoxyphenol as.the s.bs.r.te and have been found to be 35 μmol/L, 0.30 min-1, 4.5 and 37oC r.s.ectively. The Km values.for.the other.s.bs.r.te like catechol, m-cr.s.l, pyr.gallol and s.r.ngaldazine have als. been deter.ined which wer. found to be 216 μmol/L, 380 μmol/L, 370 μmol/L and 260 μmol/L r.s.ectively.
