摘要:The present invention provides a novel gene cluster containing five genes (tdiA-E) involved in indole alkaloid synthesis. Disruption of tdiB, encoding an enzyme with prenyltransferase activity, transferring dimethylallylpyrophosphate to C-2 of an indole structure, eliminated the production of the antitumor compound terrequinone A, a metabolite not known from A. nidulans . The invention further provides a method for expressing terrequinone A in a host cell and isolating purified terrequinone A therefrom.

摘要:Embodiments relate to devices, systems, methods and compositions useful for routing and tracking multiple mobile units within a microfluidic device having an inlet channel connected to a multi-way sorting junction, which is fluidly connected with a plurality of 4 or more channels, and a steering mechanism for directing the flow of the mobile units according to a predetermined algorithm. Mobile units can be routed and followed through the microfluidic device in an ordered flow, such that the mobile units are exposed to chemical environments and/or enzymatic synthesis reactions associated with the channels. Mobile units can be steered in multiple directions, between the sorting junctions and the channels by the steering mechanism by changes in flow or pressure. Some such devices, systems, methods and compositions include mobile units that can flow in both the forward and reverse directions and into each of as plurality of 4 or more channels from two sorting junctions.
