the enzyme performs substrate channeling with the 15,16-dihydrobiliverdin:ferredoxin oxidoreductase catalyzing the former catalytic step. Both enzymes transiently interact and that transfer of the intermediate is facilitated by a significantly higher binding affinity of DHBV toward phycoerythrobilin:ferredoxin oxidoreductase |

development of an on-column assay with substrate channeling for FDBRs, transient interaction of both PebA and PebB during the conversion of biliverdin IXa (BV) to phycoerythrobilin (PEB) via 15,16-dihydrobiliverdin (DHBV) |

the open-chain tetrapyrrole substrate DHBV is bound in an unexpected flipped orientation within the canonical FDBR active site. Two central aspartate residues Asp99 and Asp219 as essential for catalytic activity. In addition, the conserved Arg215 plays a critical role in substrate specificity, binding orientation, and active site integrity |
