This work is a call for attention and effort to determine the actual redox state of enzyme-bound cofactor or cosubstrate in redox reactions! https://t.co/biJ3RWGOfC @UTSAChemistry@UTSASciences@jbiolchem
Hey y'all! Check out our new paper from Ephrahime and company lending understanding to L-Tyr's amino group in the His-ligated heme enzyme tyrosine hydroxylase, clarifying its catalytic role via substrate analogs @UTSAChemistry@UTSASciences@ACScatalysis https://t.co/0rGhipjx0V
The Welch-funded project at @UTSAChemistry, led by PI Aimin Liu (@Dr_Feradical), has resulted in a new publication in the high-profile chemistry journal Angewandte Chemie. This work uncovers how the iron-containing oxindole-installation enzyme MarE shifts gears in oxygenation selectivity through structural and redox tuning, guiding distinct product outcomes from a shared substrate including the predominant dioxygenated product to the intended monooxygenated 2-oxindole scaffold for natural product biosynthesis. By revealing the true catalytic identity of MarE and delineating the roles of small-molecule effectors and loop architecture, this study advances mechanistic understanding and predictive capabilities within the oxygenase superfamily. https://t.co/PWZheXjdtV
New publication alert! Check out our findings on MarE chemistry and how our engineered loop-swapping between MarE (SLGGR) and TDO (GTGGS) showed the importance of its role in directing oxygenation outcomes! @angew_chem@UTSAChemistry https://t.co/JVAAEytc7v
Proud to celebrate Ephrahime Traore and Romie Nguyen on earning their PhDs! 🎓✨
Watching you grow as scientists has been a true privilege. You’ve tackled tough experiments, late-night writing, and endless revisions!
Excited to see where science takes you next! Congratulations!

Whoa, hey there boss! Your innovative ideas and consistent support puts your students (us!) in optimal conditions to thrive. We are very happy to see UTSA recognize your efforts! @UTSAchemistry@UTSASciences @UTSAtoday https://t.co/aGJeOMBs3o
Excited to share our new publication in JBC on the enol/keto tautomerization of oxaloacetate by ACMS decarboxylase (doi: 10.1016/j.jbc.2024.107878)! This finding highlights the need for further biological testing. #ACMSD#enzymology#Oxaloacetate#metabolism
Congratulations to UTSA Chemistry’s Yu Yung, Ian Davis, and Dr. Aimin Liu on their published article in the Journal of Biological Chemistry about “α-Amino-β-carboxymuconate-ε-semialdehyde decarboxylase catalyzes enol/keto...” Be sure to check it out! https://t.co/HVg75H9HLc
Temperature is an important factor for pathogenic protein. See how KatG regulates its activity by an N-OOH adduct and uses its MYW cofactor to direct its oxidizing power towards peroxide decomposition rather than peroxidase activity @angew_chem@UTSA
Congratulations to UTSA’s Chemistry Jiasong Li, Ran Duan, Ephrahime Traore, Romie Nguyen, Ian Davis, Wendell Griffith, and Aimin Liu on their publication in Angewandte Chemie International Edition (ACIE) about “Indole-N-Linked Hydroperoxyl Adduct of...” https://t.co/tNAtp5yVSH
New NIH grant! Join us to study amino acid metabolism, oxidation, crosslinking by metalloenzymes using Chem Biol, site-directed incorporation of noncanonical amino acids, spectroscopy, crystallography, and cryoEM (https://t.co/gNlOfU6YrU; contact: [email protected]) #ScienceJobs
We were very happy and honored to have lab alumnus Capt. Ian Davis join us for a dinner with the whole group. It was great to hear about your new work and life experiences and know that you are thriving, Ian! @GeorgiaStateU@UTSA@UTSAChemistry
The Liu lab Summer2024 pickleball competition was a great success. Our students need to work harder to improve their pickleball skills since @Dr_Feradical gave no quarter and decisively won! Can't let this happen again... @UTSAChemistry@UTSA@UTSASciences
ADO is pivotal in the regulation of oxygen sensing and thiol metabolism. We present evidence of a catalytic metal(3+)-bound superoxo intermediate, challenging the status quo of a high-valent ferryl intermediate in the thiol dioxygenase mechanism @J_A_C_S https://t.co/vCvAAqmVrq
Very sad to learn that Prof. Andrzej A. Jarzecki @CCNYChem, our collaborator on catalase-peroxidase (i.e., KatG), passed away in an accident. He was a wonderful, friendly, knowledgeable, productive, proactive, and passionate colleague. May he rest in peace!
Congrats Cassadee Stagliano, for passing your candidacy exam with flying colors! We're excited to hear about your future discoveries in the heme enzyme field @UTSA@UTSASciences@UTSAChemistry
