Research topics of the Laboratory of Protein Engineering:
Our team is focused on discovery of new bacteriolytic enzymes and studies of their structure, specificity and stability, in order to develop novel non-antibiotic antibacterial agents of wide range of applications in medicine, veterinary and industry. The enzymes selectively and efficiently eliminate pathogenic bacteria, including those which are antibiotic resistant, and may serve as modern agents for surface disinfection, diagnostic kits components and antimicrobials for human and animal therapy. Structural and physiological basic studies on regulation of enzymes activity allow for precise protein engineering and fine tune of them to specific applications and final products demands.
