Abstract

Four cDNA clones for ligninase were isolated from the cDNA library (constructed into the PstI site of E. coli vector pUC9) representing 6 day-old lignin degrading culture of Phanerochaete chrysosporium by the use of three synthetic oligonucleotide probes corresponding to partial amino acid sequences of tryptic peptides of the ligninase. Each of the three probes, 14.1, 14.2 and 25, represents a mixture of 32 12- or 14-base long oligonucleotides. Three cDNA clones hybridized with probe 14.1 but not with probe 25 or 14.2, but one cDNA clone hybridized with all of the three probes. Differential hybridization studies showed that these clones are unique to 6-day poly(A) RNA, but not to 2-day poly(A) RNA.
