摘要：

Degradation of a (beta-O-4)-(5-5') type trimer, arylglycerol-beta-(dehydrodivanillyl alcohol) ether (I) by lignin peroxidase was investigated. In the degradation of substrate (I) by the enzyme, C-alpha-C-beta cleavage, beta-O-4 bond cleavage, and beta-etherified aromatic ring (B-ring) opening products were identified as degradation products. The results showed that the B-ring of substrate (I), which sterically must be hindered more than those of arylglycerol-beta-guaiacyl and -beta-(2,6-dimethoxyphenyl) ethers, was oxidized by lignin peroxidase.
