Analysis of Phycodnaviridae Tetrapyrrole Enzymes: Subcellular Localization and Functional Divergence from Host Homologs

Steven Zehnacker, Stefano Caffarri, Guillaume Blanc…·M.I. Siponen

The paper analyzes Phycodnaviridae viral homologs of heme oxygenase-1 and Phycocyanobilin:Ferredoxin oxidoreductase to predict their subcellular localization and functional divergence from host enzymes.

Structural and functional characterization of two conserved lumenal TPM-domain proteins involved in the maturation of Photosystem II.

André Vidal‐Meireles, Soazig Malesinski, Noémie Lourenco…·Xenie Johnson

The paper identifies and characterizes two conserved TPM-domain proteins in Chlamydomonas reinhardtii, showing they are functionally redundant in PSII maturation and affect photosynthetic performance.
