recombinant metagenomically derived enzymes PcyX-EBQ and PcyX-ECK are functional FDBRs catalysing the reduction of BV via 5,16-dihydrobiliverdin (DHBV) to phycoerythrobilin (PEB). The rate determining step in the PcyX-catalysed reaction is the conversion of the intermediate DHBV to the final product PEB. Enzyme PcyX_ECK forms 3(E/Z)-PPhiB as side products
