Perspectives on the use of metabolic engineering in beta-lactam antibiotic biosyntheses
Pitkina, Anastasiya ; Kyslík, Pavel (advisor) ; Nunvář, Jaroslav (referee)
At present beta-lactams achieve leading positions among antibiotics as to the volume of sales and importance of utilization. This thesis compares selected industrially used chemical and enzymatic ways of production of beta-lactam antibiotics and further concentrates on the application of relatively novel approach of metabolic engineering in beta-lactam biosyntheses. Currently some of the described methods based on metabolic engineering are already being applied in production processes,whereas other technologies remain rather a theoretical possibility.
Application of tailor-made enzymes for biosyntheses of beta-lactam antibiotics
Schneiderová, Michaela ; Kyslík, Pavel (advisor) ; Vopálenská, Irena (referee)
Nowadays beta-lactam antibiotics are widely used as bacteriostatic agents. The chemical synthesis of antibiotics or its derivatives could be replaced with biocatalysis. This work deals with basics of industrial synthesis beta-lactam antibiotics and, mainly, with used enzymes. This work acquainted with methodes used in enzyme modifications and improving, so they could fit the best for the industrial syntheses.

Purifikace a charakterizace penicilin-G-acylasy exprimované v Escherichia coli a Pichia pastoris
Marková, Zdenka ; Marešová, Helena ; Kyslík, Pavel
The pga gene coding for penicillin G acylase from strain E. coli RE3 was cloned on pPICZA plasmid and expressed in the yeast Pichia pastoris X33. The enzyme was purified from both strains and further characterized
Správné a chybné skládání chimérní pyranosa-2-oxidasy exprimované v E. coli
Marešová, Helena ; Kyslík, Pavel
Recombinant and chimeric pyranose 2-oxidases from different parental strains (Trametes ochracea and pubescens) were expressed in E. coli and formation of inclusion bodies were followed. The two, closely-related enzymes differ in folding into an active form under identical growth conditions
