  • Patent number: 8124390
    Abstract: In accordance with the present invention, a novel aromatic prenyltransferase, Orf2 from Streptomyces sp. strain CL190, involved in naphterpin biosynthesis has been identified and the structure thereof elucidated. This prenyltransferase catalyzes the formation of a C—C bond between a prenyl group and a compound containing an aromatic nucleus, and also displays C—O bond formation activity. Numerous crystallographic structures of the prenyltransferase have been solved and refined, e.g., (1) prenyltransferase complexed with a buffer molecule (TAPS), (2) prenyltransferase as a binary complex with geranyl diphosphate (GPP) and Mg2+, and prenyltransferase as ternary complexes with a non-hydrolyzable substrate analogue, geranyl S-thiolodiphosphate (GSPP) and either (3) 1,6-dihydroxynaphthalene (1,6-DHN), or (4) flaviolin (i.e., 2,5,7-trihydroxy-1,4-naphthoquinone, which is the oxidized product of 1,3,6,8-tetrahydroxynaphthalene (THN)). These structures have been solved and refined to 1.5 ?, 2.25 ?, 1.95 ? and 2.
