Abstract: The present invention relates to an in vitro or in vivo process for producing a glucuronide comprising a glucuronic acid moiety bound to a phenolic hydroxyl group or a phenolic carboxyl group. Also provided are expression vectors, nucleic acids, polypeptides, and recombinant microbial cells useful in carrying out the process and prodrugs produced by the process.

Abstract: The present disclosure provides for an expression system for the production of blue pigment indigoidine. The system comprises a heterologous host cell, a DNA sequence encoding a Sc-IndB protein, and a DNA sequence encoding a Sc-IndC protein. The system may be configured for the co-expression of the Sc-IndB and Sc-IndC. DNA sequences encoding the Sc-IndB and Sc-IndC may be provided on at least one vector. Alternatively, the DNA sequences encoding the Sc-IndB and Sc-IndC may optionally be integrated into the genome of the heterologous host genome. The expression system may further comprise a sfp gene or a PPTase.

Abstract: The present disclosure relates to an isolated or purified nucleotide sequence comprising a cDNA sequence of an rdc2 at least 60%, 70%, 90%, 95%, 98%, or 100% identical to SEQ ID NO. 1. In a second embodiment, the invention provides for a flavin-dependent halogenase comprising an amino acid sequence of an Rdc2 halogenase at least 60%, 70%, 90%, 95%, 98%, or 100% identical to SEQ ID NO. 2. In related embodiments there are provided herein methods for halogenating compounds by using an Rdc2 halogenase of the present invention.
