| Abstract | The aim of this work has been to study the substrate specificity of two aromatic peroxygenases concerning polyaromatic compounds of different size and structure as well as to identify the key metabolites of their oxidation. Thus, we report here on new pathways and reactions for 2-methylnaphthalene, 1-methylnaphthalene, dibenzofuran, fluorene, phenanthrene, anthracene and pyrene catalyzed by peroxygenases from Agrocybe aegerita and Coprinellus radians (abbreviated as AaP and CrP). AaP hydroxylated the aromatic rings of all substrates tested at different positions, whereas CrP showed a limited capacity for aromatic ring-hydroxylation and did not hydroxylate phenanthrene but preferably oxygenated fluorene at the non-aromatic C9-carbon and methylnaphthalenes at the side chain. The results demonstrate for the first time the broad substrate specificity of fungal peroxygenases for polyaromatic compounds, and they are discussed in terms of their biocatalytic and environmental implications. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
