Our home department of Molecular Biology & Biochemistry at UC Irvine is looking to hire a new tenure-track assistant professor in the broad area of structural biology. Come be our colleague! https://t.co/SRSQEqHGiP Please apply and/or share this post! @UCIBioSci; @UCIrvine

Our latest work on the nitrogenase-like methylthio-alkane reductase is now out @NatureCatalysis https://t.co/NxFGaYg7Xb We biochemically and structurally characterized the methylthio-alkane reductase, a metalloenzyme that can produce ethylene from organic sulfur compounds.

@HuRibbe Lab reunion at the Molybdenum Tungsten Enzyme Conference #MoTEC on the Queen Mary in Long Beach, CA. With great talks by Markus and Yilin.

Great talk by Joe Rebelein yesterday evening at the MoTEC 2025 at long beach! Congratulations to the EMBO young investigator lecture! Much deserved 👍

Congratulations to Bryan Neumann from our collaborator Shane Gonen’s lab on receiving the Barbara K. Burgess Postdoctoral Fellowship Award — a well-deserved honor! @GonenShane @HuRibbe @UCIBioSci

Using spectroscopic and structural approaches we gained new insights into the role of #ferredoxins in N2 fixation. Just published in @ChemEurJ: https://t.co/pbeYoZDNzE! Great work by @HollyGAddison and fantastic excellent with @AJPierik.

You may ask: “why study ancient enzymes? Who cares what life looked like 3 billion years ago?” Because evolution may hold answers to problems we still struggle with, and it can guide our efforts. New paper from our lab! 🧵

Our second paper was published online within the same week 😊! Thanks everyone for their hard work! @ScienceAdvances, @HuRibbe, @UCIBioSci, @UCIChemistry Heterologous synthesis of a simplified nitrogenase analog in Escherichia coli | Science Advances

Excited to share our latest work highlighting the crucial role of belt-sulfur mobilization in nitrogenase catalysis. A big thank you to everyone who contributed to this effort! @ChemCatalysis, @HuRibbe, @UCIBioSci, @UCIChemistry https://t.co/ytxyWWhjcd

I'm truly excited to announce our new publication in @Nature unraveling a central picture of the Methyl-coenzyme M reductase (MCR) activation machinery and it's strong ATP dependency - kudos to @AnujR2d2 for the fantastic illustration! LINK: https://t.co/OmMRWWtNR8

wondering how does this species survive in the wild.

Allow me to introduce to you ... The bucket!

Congrats Leo & Joe! This is awesome!

Our latest work on a #nitrogenase-like enzyme, the methylthio-alkane reductase which surprisingly also contains large nitrogenase metalloclusters, the P-cluster and the [Fe8S9C]- (L)-cluster is now online: https://t.co/k6E8Sf1A99 Have a look at the 🧵 by @AnaLagoMaciel.

Our story made the cover! Really proud of it. Thank you so much Nature Catalysis for supporting our work! @NatureCatalysis, @HuRibbe, @UCIBioSci, @UCIChemistry https://t.co/OFeZGHKy8S https://t.co/kD3inCKbY2

Congrats for finally demonstrating the expression of metallocluster replete nitrogenases in E. coli. That's a fantastic advancement!

Our years of work on nitrogenase assembly paid off! So proud of this paper, which demonstrates the heterologous expression of an active nitrogenase. Thanks to everybody involved for a great team effort! @NatureCatalysis, @HuRibbe, @UCIBioSci, @UCIChemistry https://t.co/cU2FnPCtlh

This is the most important video you'll see today!

We are proud to announce a $50M gift from Charlie Dunlop, founder of Ambry Genetics. Our school will now be known as the Charlie Dunlop School of Biological Sciences. This gift will significantly impact our school and the broader scientific community. #DunlopSchool @FrankLaFerla
