Normal progression of the translating ribosome through +X+ motifs (or any other sequences) in the absence of a macrolide. Peptide bond formation in the PTC occurs normally (black arrow). b Macrolide-induced inhibition of peptide bond formation in the PTC of a ribosome progressing through +X+ sequence (red cross).

A new paper in collaboration with the Polikanov group published in Nature communications! Highlighting the the context-specific action of macrolide antibiotics. 

Congratulations to Max.

Alex presenting his thesis inside a classroom

We are thrilled to celebrate Alex, who has successfully defended his doctoral thesis, “The impact of depleting the essential bacterial enzyme peptidyl-tRNA hydrolase on translation”. This achievement marks a huge step forward for him and an exciting highlight for our lab. 

Alex’s research uncovered how cells respond when a universally essential translation-quality control enzyme is removed. These insights continue to deepen our understanding of translation. 

Congratulations, Dr. Alex!

Lab members pose in front of the MBRB staircase with Kasra

We are proud to share that Kasra has successfully defended his doctoral thesis, “Orthogonal Protein Synthesis by Ribosomes with an Integrated mRNA“. This work is a major milestone for him and our lab. 

His research reimagined how ribosomes can be engineered to work with integrated mRNAs, advancing the field of orthogonal protein synthesis and opening new possibilities in synthetic biology. 

Congratulations, Dr. Kasra!

Members of the lab take a photo together at the conference in Pacific Grove

Triennial “Ribosome” meeting took place in Pacific Grove, CA on 22-27 of June bringing together the leading scientists in the field of protein synthesis. The research from our lab was represented with four posters and two talks.

A new paper in collaboration with the groups of Gerard Wright (McMaster University) and Yury Polikanov (UIC) is published today in Nature! Lariocidin, the first lasso peptide targeting bacterial translation and a promising new lead for antibiotic development, is in the news today. Congratulation to all authors!

Lab volleyball season has just started at the North Beach!

Dr. Mankin presented the lab’s research at UIC Spark Talks. SparkTalks are UIC’s take on faculty lightning talks, and provide an opportunity for faculty, leaders, and others across campus to learn about the exciting activity happening in every corner of UIC.

Dorota's potluck trophy

Dorota again won in the “Best savory dish” category at CBS Potluck. Congratulations from the team! We are all looking forward to taste new masterpieces by the Chef!
