Abstract: PrkC is an important Ser/Thr membrane kinase of Staphylococcus aureus able to bind peptidoglycans through extra-cellular domains, denominated as PASTA. Upon peptidoglycan binding, PrkC is activated and stimulates bacterial growth and revival from latency. The entire extra-cellular region of PrkC (residues 378-664), containing three predicted PASTA domains and an extra-domain of unknown function, has been successfully crystallized using vapor-diffusion methods. The structure has been solved by Multiwavelength Anomalous Dispersion and refinement is in progress.
