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 mechanism of ccpA to evaluate the interaction with the PknB kinase when stimulated with ß-lactam antibiotics.

Cloning

Theoretical Part Design

This part was codon optimised for human cell lines and synthesised by Eurofins.

Characterization

The correct ccpA functionality was analyzed by composing a gene cassette where its placed downstream of the constitutuve CMV promoter and fused with the reporter gene mRuby2 to assess by indication with ß-lactam antibiotics the ccpA localization based on the fluorescent signal. Please visit the K5317019 registry entry to view the results.
