A CozE Homolog Contributes to Cell Size Homeostasis of Streptococcus pneumoniae
Stamsås, Gro Anita; Restelli, Marine; Ducret, A; Freton, Celine; Garcia, Pierre Simon; Håvarstein, Leiv Sigve; Straume, Daniel; Grangeasse, Christophe; Kjos, Morten (Peer reviewed; Journal article, 2020) -
Characterization of the penicillin-binding proteins in Streptococcus oralis Uo5
Fykse, Silja Kavlie (Master thesis, 2017)In the search for new antibiotics the mechanism behind cell division has been studied for decades. The extensive use of antibiotics has led to the development of resistant bacteria, a problem that has become a global threat. ... -
Class A PBPs have a distinct and unique role in the construction of the pneumococcal cell wall.
Straume, Daniel; Piechowiak, Katarzyna Wiaroslawa; Olsen, Silje; Stamsås, Gro Anita; Berg, Kari Helene; Kjos, Morten; Heggenhougen, Maria Victoria; Alcorlo, Martín; Hermoso, Juan A.; Håvarstein, Leiv Sigve (Peer reviewed; Journal article, 2020) -

Overexpression of the fratricide immunity protein ComM leads to growth inhibition and morphological abnormalities in Streptococcus pneumoniae
Straume, Daniel; Stamsås, Gro Anita; Salehian, Zhian; Håvarstein, Leiv Sigve (Journal article; Peer reviewed, 2017)The important human pathogen Streptococcus pneumoniae is a naturally transformable species. When developing the competent state, it expresses proteins involved in DNA-uptake, DNA-processing and homologous recombination. ... -
Penicillin-binding protein PBP2a provides variable levels of protection towards different β-lactams in Staphylococcus aureus RN4220
Fergestad, Marte Ragnhild Ekeland; Stamsås, Gro Anita; Angeles, Dana Morales; Salehian, Zhian; Wasteson, Yngvild; Kjos, Morten (Peer reviewed; Journal article, 2020)Methicillin-resistant Staphylococcus aureus (MRSA) is resistant to most β-lactams due to the expression of an extra penicillin-binding protein, PBP2a, with low β-lactam affinity. It has long been known that heterologous ... -
Prevention of EloR/KhpA heterodimerization by introduction of site-specific amino acid substitutions renders the essential elongasome protein PBP2b redundant in Streptococcus pneumoniae
Winther, Anja Ruud; Kjos, Morten; Stamsås, Gro Anita; Håvarstein, Leiv Sigve; Straume, Daniel (Peer reviewed; Journal article, 2019) -
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. ...
