    • Crystal Structures of Pseudomonas aeruginosa GIM-1: Active-Site Plasticity in Metallo-beta-Lactamases 

      Borra, Naga Pardha Saradhi; Samuelsen, Ørjan; Spencer, James; Walsh, Timothy R.; Lorentzen, marit sjo; Leiros, Hanna-Kirsti S. (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Metallo- -lactamases (MBLs) have rapidly disseminated worldwide among clinically important Gram-negative bacteria and have challenged the therapeutic use of -lactam antibiotics, particularly carbapenems. The blaGIM-1 gene, encoding one such enzyme, was first discovered in a Pseudomonas aeruginosa isolate from 2002 and has more recently been reported in Enterobacteriaceae. Here, we present crystal ...

    • Investigating the role of residues W228 and Y233 in the structure and activity of the GIM-1 metallo-beta-lactamase. 

      Skagseth, Susann; Carlsen, Trine Josefine Olsen; Bjerga, Gro Elin Kjæreng; Spencer, James; Samuelsen, Ørjan; Leiros, Hanna-Kirsti S. (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-12-07)
      Metallo--lactamases (MBLs) hydrolyze virtually all -lactam antibiotics, including penicillins, cephalosporins, and carbapenems. The worldwide emergence of antibiotic-resistant bacteria harboring MBLs poses an increasing clinical threat. The MBL German imipenemase-1 (GIM-1) possesses an active site that is narrower and more hydrophobic than the active sites of other MBLs. The GIM-1 active-site ...
