Cell-shape regulation in Streptococcus pneumoniae : EloR/KhpA, a new regulatory pathway administering cellelongation
Winther, Anja Ruud (PhD Thesis;2020:36, Doctoral thesis, 2020)The oval shaped Streptococcus pneumoniae utilizes both septal and peripheral peptidoglycan (PG) synthesis in order to maintain its shape. The protein complexes responsible for synthesizing PG are called the elongasome and ... -
Molecular mechanisms of pneumococcal fratricide
Eldholm, Vegard (PhD Thesis;2010:13, Doctoral thesis, 2010)The bacterium Streptococcus pneumoniae is endowed with the ability to take up naked DNA from the surroundings and recombine this DNA into the chromosome. This property, termed competence for natural genetic transformation, ... -
Natural genetic transformation: development of a new genetic tool for Streptococcus thermophilus
Blomqvist, Trinelise (PhD Thesis;2010:16, Doctoral thesis, 2010)Lactic acid bacteria (LAB) have been used in fermentation of foods for hundreds or even thousands of years. During the last decade the genome sequences of a number of commercially important LAB species and strains have ... -
Regulation of expression, purification and structural determination of the cross-wall splitting protein PcsB in Streptococcus pneumoniae
Stamsås, Gro Anita (PhD Thesis;2015:8, Doctoral thesis, 2018-04-24)The human pathogen Streptococcus pneumoniae causes approximately 1.6 million deaths per year. Hence, it is of great concern that the bacterium`s resistance against antibiotics has increased dramatically in recent decades. ...
