CcpA

Usage and Biology

The regulatory functions of CcpA are modulated by phosphorylation by serine/threonine kinases, which can affect its DNA-binding activity and thus its ability to regulate target genes. This phosphorylation-dependent mechanism enables S. aureus to adapt to different environmental conditions, thereby increasing its survivability and virulence (Liao et al., 2022). We used this bacterial protein to evaluate the interaction with the PknB kinase.

Cloning

Theoretical Part Design

Placing the mRuby2 (K5317001) reporter gene behind ccpA allows for visualisation of expression of the protein of interest. Gene of interest was codon optimised for human cell lines.
