Active-site serine D,D-transpeptidases belonging to the penicillin-binding protein family (PBPs) have been considered for a long time as essential for peptidoglycan cross-linking in all bacteria. However, bypass of the PBPs by an L,D-transpeptidase (Ldt(fm)) conveys high-level resistance to β-lactams of the penam class in Enterococcus faecium with a minimal(More)
Zinc (Zn(2+)) homeostasis is critical for pathogen host colonization and invasion. Polyhistidine triad (Pht) proteins, located at the surface of various streptococci, have been proposed to be involved in Zn(2+) homeostasis. The phtD gene, coding for a Zn(2+)-binding protein, is organized in an operon with adcAII coding for the extracellular part of a Zn(2+)(More)
