A cluster of genes encoding major isozymes of lignin peroxidase and manganese peroxidase from the white-rot fungus Trametes versicolor
(1996) In Gene 170(1). p.31-38- Abstract
- A gene cluster from the white-rot basidiomycete Trametes (Coriolus) versicolor (Tv) PRL 572 containing three structural genes, LPGIII, LPGIV and MPGI, was characterized. The genes are arranged in the same transcriptional direction, within a 10-kb region, and found to encode quantitatively dominant isozymes of lignin peroxidase (LP) and manganese peroxidase (MP). The second gene in sequence, LPGIV, predicts a 346-amino-acid (aa) mature polypeptide (36.9 kDa, pI 4.31) which is identical with the partial aa sequence information available on the LP12 isozyme (43.1 kDa, pI 3.27). The first gene, LPGIII, encodes a 341-aa polypeptide (36.1 kDa, pI 3.93) which has not been identified at the protein level. However, the similarity to LPGIV would... (More)

The first gene, LPGIII, encodes a 341-aa polypeptide (36.1 kDa, pI 3.93) which has not been identified at the protein level. However, the similarity to LPGIV would suggest that the predicted product is an LP-type enzyme. LPGIII andLPGIV are homologous to the tandemly arranged genes LPGII and LPGI, respectively, recently described by Jonsson and Nyman [Biochim. Biophys. Acta 1218 (1994) 408-412]. The homologous genes, LPGIII/LPGII and LPGIV/LPGI, are 99% and 96% identical in sequence, respectively, and are predicted to encode identical polypeptides, since base substitutions in the predicted exons are all synonymous. The third gene, MPGI, is different in intron-exon organization and predicted to be disrupted by five rather than six introns, as are the LP genes. The deduced polypeptide, 339 aa in size (35.9 kDa, pI 4.07), is identical with the partial aa sequence information available for isozyme MP2 (44.5 kDa, pI 3.09). The MPGI- and LPGIV-encoded polypeptides are 70% identical in sequence which suggests that MP and LP from Tv may be regarded as members of the same family within the plant peroxidase superfamily. Most importantly, this study identifies a gene encoding the MP2 isozyme, and further shows that genes encoding MP and LP can be closely linked on the chromosome and may be coordinately transcribed.
