- Last Friday was the defense of my PhD thesis entitled "Structural basis of anaerobic enzymes mediated by noncanonical metalloclusters" after 4 yrs at the @synmikro.bsky.social 🎓🎓 Big thanks to my supervisor @schullerjm.bsky.social and the whole Schuller lab for their continuous and massive support!
- Out of the lab, words cannot express the impact that @ekaterinajalomo.bsky.social, my (now growing) family and friends from Marburg and Mexico have had along the road! To everyone who was part of it, thanks!

- Reposted by Fidel Ramírez-AmadorOur latest work on the nitrogenase-like methylthio-alkane reductase, which specifically reduces reduces carbon-sulfide bonds is now out @natcatal.nature.com: doi.org/10.1038/s419.... We find for the first time large #nitrogenase metalloclusters (P- and L-cluster) outside nitrogenases.
- Microbial enzymes hold the key to greener plastics! Rhodospirillum rubrum can produce ethylene without releasing CO₂. A team @rebeleinlab.bsky.social purified the enzyme and solved its structure, an important step towards #SustainableChemistry.

We achieved this by using the enzyme Huc to oxidize ambient hydrogen. This results in a continuous low-level power from air and higher outputs with industrial waste gases.
- Reposted by Fidel Ramírez-AmadorMetal ions are universally required for life, and many of the foundational principles of metal homeostasis have emerged from studies of microbial systems. In this review, I provide a introductory overview targeted to those new to the field. #MicroSky #Metals rdcu.be/eycU2

- Reposted by Fidel Ramírez-AmadorNew paper from the lab from Sriram Garg in my group. We introduce a general substitution matrix for structural phylogenetics. I think this is a big deal, so read on below if you think deep history is important. academic.oup.com/mbe/advance-...
- Reposted by Fidel Ramírez-AmadorProud to present the lab's latest work. The full structure of the sodium translocating methyltransferase (Mtr) bound to a small oxygen-responsive small protein MtrI. Work by Tristan and together with @schmitzstreitslab.bsky.social . www.biorxiv.org/content/10.1101/2025.06.02.657420v1
- Reposted by Fidel Ramírez-AmadorCLUSTERING FOR METHANE Nice write-up @natcatal.nature.com of our recent article on MCR activation 🙏🏻 www.nature.com/articles/s41...
- Reposted by Fidel Ramírez-AmadorLeveraging spectroscopic and structural approaches we obtained new insights into the role of #ferredoxins in N2 fixation. Just published in Chemistry – A European Journal: doi.org/10.1002/chem...! Great work by Holly Addison. Fantastic collaboration with Antonio Pierik on the EPR characterization.
- Reposted by Fidel Ramírez-AmadorHappy to present the lab latest work, today from the green-side. The ultimate PSII assembly intermediate that directly precedes incorporation of the Mn4O5Ca cluster and formation of the OEC. Psb32 binds to PsbV, challenging the assumption the extrinsic subunits all associate spontaneously in-vivo.
