Having experienced @Dr_Feradical’s mentorship firsthand, our group couldn't be happier to see this vision realized👏 So happy for our buddies across the hall, who will get to benefit from this new NIH award. Rooting for our SA peers @UTSAChemistry from Philly! Exciting times 🥳🥳

[Aimin Liu @Dr_Feradical]

A dream realized for UTSA!🎓✨ Huge congrats to Dr. Joo L. Ong for his leadership in securing a new NIH/NIGMS T32 grant and Dean Ambika Mathur for her guidance. Honored to have supported the application and grateful to stay involved in an advisory role.

🎉Thrilled to receive an NSF CAREER Award! Many thanks to @NSF and the CLP program for supporting our research, education, and outreach efforts. Also deeply grateful to the Wang lab members, collaborators, colleagues, and the university @UGAResearch for making this possible!🙏

[Aimin Liu @Dr_Feradical]

Huge congrats to our newest graduates, Drs. Cassadee Stagliano and Ran Duan 🎓! Despite being ahead of schedule due to our relocation, they crushed their thesis defenses and did exceptionally well. So happy they're sticking around to finish current projects before moving on! 👏

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

[Aimin Liu @Dr_Feradical]

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!

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

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
