I'm thankful that society journals, @microbiologysociety.org, @femsmicro.org, & @amiposts.bsky.social, are experimenting with new publication models to encourage shorter narratives like this.

🆕New pre-print!🆕 This year seems to be about tying up stories. This time it's by former post-doc Debika Choudhury, who put together a mini story.

In this paper we describe how a narrow-spectrum antimicrobial peptide #AMP #antimicrobial can be re-purposed & modified as a probe to manipulate mixed microbial system from the top down. We hope this approach will find wider adoption in studying and engineering various #microbiota #microbiomes.

Engineered antimicrobial-derived peptides to manipulate mixed microbial systems | Microbiology Spectrum We demonstrate a novel approach for top-down manipulation of microbial co-cultures by leveraging the narrow-spectrum activity of a class IIa bacteriocin (bacterial-derived antimicrobial peptide). We e...

🆕New paper🗞️! Sometimes a paper can be in a works for a long time because trainees leave the group and their priorities change. But I'm so glad that former post-doc Vikas Trivedi found time to finish this paper with @vandeventerjim.bsky.social and me! @tufts.edu

Reversal of the Leloir pathway to promote galactose and tagatose synthesis from glucose Love and Toomey et al. demonstrate a whole-cell process that converts glucose directly to the rare sugar D-tagatose by reversing the Leloir pathway. Structural and biochemical analyses reveal how a sp...

New paper from the lab! We show a new pathway to make tagatose from glucose! After assessing several pathways, we identified a phosphatase specific to gal-1-P to enable this route. We also perform modeling to understand the molecular determinants of specificity.

Engineered antimicrobial-derived peptides to manipulate mixed microbial systems Due to complexity of microbial communities and coarseness of currently available manipulation techniques (e.g. transplantation, antibiotic-treatment), it is often difficult to fully elucidate the inte...

🚨New manuscript alert!🚨We show that a natural, bacterial-derived, #antimicrobial #AMP can be used and engineered for targeted manipulation of specific species in a microbial community from the top-down! #microbiome. Thanks to @vandeventerjim.bsky.social for helping!

High throughput screening of eukaryotic release factor 1 variants to enhance noncanonical amino acid incorporation Noncanonical amino acids (ncAAs) enable diversification of protein functions, but the efficiency of genetic code expansion (GCE) in eukaryotes is hindered by competition between suppressor tRNAs and r...

Today, I’m grateful that I can finally share Briana Lino’s @blino237.bsky.social work on engineering eukaryotic release factor 1 (eRF1) for enhanced noncanonical amino acid incorporation. I highlight some key findings in this thread (1/n).

Tufts Will Be Tuition-Free for U.S. Families Earning Less Than $150,000 Tufts University announces that U.S. students from families earning less than $150,000 will not have to pay undergraduate tuition.

Today, I'm grateful to Tufts University--the university is trying to do good in the world, at a time when it's very easy for institutions of higher learning to stray wildly from their core missions.

(Disclosure: Tufts is my employer)

A Novel Phosphatase Reverses the Leloir Pathway to Promote Tagatose Synthesis from Glucose D-Tagatose is a natural, low-calorie, rare monosaccharide that has gained substantial interest as an alternative sweetener. It offers numerous benefits, including a low glycemic index, prebiotic prope...

New pre-print from the lab! We show for the first time that tagatose can be synthesized from glucose! After assessing several pathways, we identified a phosphatase specific to gal-1-P. We also perform modeling to understand the molecular determinants of specificity.

Here are the nearly 2,500 medical research grants canceled or delayed by Trump Some cuts have been starkly visible, but the country’s medical grant-making machinery has also radically transformed outside the public eye.

Great piece @nytimes.com with a database of thousands of NIH grants ended or delayed.

No matter the intention, the effects are clear: a huge slowdown in biomedical research into diseases & new therapeutics.

Share with your Rep & Senators, and spread awareness!

Finally, we show that engineered spores can be used to degrade plastic PET films #plasticdegradation

We compare coat proteins for surface availability and protection from inactivating agents (e.g., heat, protease), and their effect on sporulation efficiency. We also assess how different coat proteins can be co-utilized to increase display levels.

Allelic tagging allows us to examine the activation timing and strength of promoters associated with spore coat structural proteins.

In addition, this work investigates scarless allelic tagging of spore coat proteins using genome editing by co-transformation, analyzing factors affecting genome editing by congression.

🚨🆕New manuscript🆕🚨from the lab!! Started by @biotechalchemist.bsky.social and completed by Todd Chappell. This work assesses the utility of >30 #spore coat proteins for #surfacedisplay - almost 3x currently described! We found that SscA is a great carrier not used before‼️
