Título: | The singular properties of photosynthetic cytochrome c550 from the diatom Phaeodactylum tricornutum suggest new alternative functions |

CSIC ORCID | Fecha de publicación: | nov-2018 | Editor: | Wiley-Blackwell | Citación: | Physiologia Plantarum, (2018) | Resumen: | Cytochrome c550 is an extrinsic component in the luminal side of photosystem II in cyanobacteria, as well as in eukaryotic algae from the red photosynthetic lineage including, among others, diatoms. We have established that cytochrome c550 from the diatom Phaeodactylum tricornutum can be obtained as a complete protein from the membrane fraction of the alga, although a C‐terminal truncated form is purified from the soluble fractions of this diatom as well as from other eukaryotic algae. Eukaryotic cytochromes c550 show distinctive electrostatic features as compared with cyanobacterial cytochrome c550. In addition, co‐immunoseparation and mass spectrometry experiments, as well as immunoelectron microscopy analyses, indicate that although cytochrome c550 from P. tricornutum is mainly located in the thylakoid domain of the chloroplast –where it interacts with photosystem II–, it can also be found in the chloroplast pyrenoid, related with proteins linked to the CO2 concentrating mechanism and assimilation. These results thus suggest new alternative functions of this heme protein in eukaryotes. | Versión del editor: | https://doi.org/10.1111/ppl.12888 | URI: | http://hdl.handle.net/10261/172832 | DOI: | 10.1111/ppl.12888 |
