Aromatic hydroxylation of indan by o-xylene-degrading Rhodococcus sp. strain DK17

Appl Environ Microbiol. 2010 Jan;76(1):375-7. doi: 10.1128/AEM.01745-09. Epub 2009 Oct 30.

Abstract

The metabolically versatile Rhodococcus sp. strain DK17 utilizes indan as a growth substrate via the o-xylene pathway. Metabolite and reverse transcription-PCR analyses indicate that o-xylene dioxygenase hydroxylates indan at the 4,5 position of the aromatic moiety to form cis-indan-4,5-dihydrodiol, which is dehydrogenated to 4,5-indandiol by a dehydrogenase. 4,5-indandiol undergoes ring cleavage by a meta-cleavage dioxygenase.
