PknB
Usage and Biology
PknB is a eukaryote-like serine/threonine kinase from Staphylococcus aureus that plays an important role in the bacterial response to antibiotics, particularly beta-lactams, via its PASTA domain (Stehle et al.2012). PknB is a membrane-localized protein consisting of an N-terminal cytosolic kinase domain, a central transmembrane segment, and three C-terminal extracellular PASTA domains. The PASTA (penicillin-binding protein and serine/threonine kinase-associated) domain plays a critical role in the recognition and binding of beta-lactam antibiotics (Stehle et al.2012). Upon binding these compounds, the PASTA domain initiates a signaling cascade by inducing the N-terminal kinase domain autophosphorylation. This activation leads to the initiation of downstream signaling pathways (Cheung et al.2010). In S. aureus, this mechanism is critical for the early detection of antibiotics and helps the bacteria adapt to antibiotic stress (Sauer et al. 2018).
Cloning
Theoretical Part Design
The sequence of pknB was obtained from S. aureus. The construct was codon optimized for human cell lines and synthesized by Eurofins.

Characterization
The kinase was analyzed by composing a gene cassette where its placed upstream of the reporter gene EGFP to assess the ß-lactam dependent effect based on the fluorescent signal. Please visit the K5317018 registry entry to view the results.
