Tk. Chakraborty et al., Accumulation of a natural substrate of laccase in gills of Pleurotus florida during sporulation, CURR MICROB, 41(3), 2000, pp. 167-171
During sporulation, laccase activity of Pleurotus florida decreased to a mi
nimum level in spite of increase in the number of isozymes. An endogenous l
accase substrate was detected especially in the gill structure of the sporo
phore, which competitively inhibited oxidation of guaiacol by the enzyme du
ring in vitro assay. Appearance of the laccase substrate in the gill struct
ure may be linked with the sporulation phenomenon.
