Sortase-Mediated Pilus Fiber Biogenesis in Streptococcus pneumoniae

TL;DR: It is shown that SrtC-1 is the main pilus-polymerizing transpeptidase, and electron microscopy analyses of RrgB fibers reconstituted in vitro reveal they structurally mimic the pneumococcal pilus backbone.
Journal ArticleDOI

Mutations in the active site of penicillin-binding protein PBP2x from Streptococcus pneumoniae. Role in the specificity for β-lactam antibiotics

TL;DR: In vitro data presented here are in agreement with the distinct resistance profiles mediated by these mutations in vivo and underline their role as powerful resistance determinants.
Journal ArticleDOI

Crystal structure of penicillin-binding protein 1a (PBP1a) reveals a mutational hotspot implicated in beta-lactam resistance in Streptococcus pneumoniae.

TL;DR: An analysis of P BP1a sequences from drug-resistant clinical strains in light of the structure reveals the existence of a mutational hotspot at the entrance of the catalytic cleft that leads to the modification of the polarity and accessibility of the mutated PBP1a active site.
Journal ArticleDOI

Structure-Based Phylogeny of the Metallo-β-Lactamases

TL;DR: The presence of genes from Eubacteria, Archaebacteria, and Eukaryota on that tree is consistent with a very ancient origin of the metallo-β-lactamase family.
