Basidiomycete enzyme

In a number of species of Basidiomycetes enzymes are present which appear to be specific for the y-glutamyl derivatives occurring in the same species. However, it seems more likely that these enzymes are involved in degradation rather than in biosynthesis.

Lenthionine has the characteristic shiitake flavor. It is formed from the precursor, lentinic acid 14 by complex reactions involving a C-S lyase enzyme.30 Cyclic polysulfides occur in other Basidiomycete mushrooms (Genus Micromp-hale and Colly bid), in some red alga, and in seeds of Parkia speciosa. The latter contain lenthionine and 1,2,4-trithiolane (1,2,4-trithiacyclopentane) 17 as well as compounds with 4, 5, or 6 sulfur atoms.31 These seeds are valued in Indonesia for a unique, onion-like odor. Djenkolic acid and dichrostachinic acid S -[(2-carboxy-2-hydroxyethylsulfonyl)-methyl]cysteine are converted by a C-S lyase enzyme to cyclic polysulfides djenkolic acid yields 1,2,4-trithiolane and 1,2,4,6-tetrathiepane the latter is also formed from dichrostachinic acid.32...

This heme-dependent enzyme [EC 1.11.1.13] catalyzes the reaction of two Mn + with two and hydrogen peroxide to generate two Mn + and two water. The enzyme participates in the oxidative degradation of lignin in white rot basidiomycetes. 

The purpose of the present paper is to describe the aromatic ring cleavage of lignin substructure model compounds by white-rot basidiomycetes and by lignin peroxidase of P. chrysosporium. The aromatic ring cleavage of synthetic lignin (DHP) by the enzyme will also be described. 

Analysis of the genes for four cellulases of the basidiomycete T. reesei showed that these proteins had a bifunctional organization remarkably similar to that of Cex and CenA of C. fimi, and again with reversal of domain order in pairs of the four enzymes (16).
