RiPP biosynthesis and cytochrome-associated precursor peptides
Olivia is studying TtlA1, an alternative cytochrome-containing precursor in a newly identified GABAtide RiPP biosynthetic pathway. Her work centers on construct design, heterologous expression, purification strategy, and sample preparation for downstream biochemical characterization.
- Designed and assembled constructs in pETDuet using Gibson assembly, then verified sequences and transformed into E. coli BL21.
- Optimized expression and Strep-Tactin XT purification while troubleshooting low-yield behavior in an unusual cytochrome-associated C-terminal domain.
- Prepared samples for NanoDrop and MALDI-MS to support characterization of post-translational modification.
