GraR
Usage and Biology
GraR is known for its role in β-lactam resistance by upregulating cell wall biosynthesis genes, altering cell wall composition, and increasing expression of ABC-transporters (El-Halfawy et al., 2020; Yang et al., 2012; Meehl et al., 2007). The GraSR system is a two-component regulatory system that controls the expression of many genes involved in stress response, cell wall metabolism and virulence pathways in Staphylococcus aureus (Falord et al., 2011).
Accordingly, GraR functions as a transcription factor and our cell-based antiobiotics sensor utilises it as such by aiming for its PknB-dependent phyosphorylation (K5317013).

Characterization
The GraR functionality was analyzed by composing a gene cassette fused with the reporter gene mRuby2 K5317001 to assess GraR cell localization based on the fluorescent signal with unstimulated ampicillin conditions. Please visit the K5317020 registry entry to view the results.
