The challenges of resistance to antibiotics and resistance to herbicides have much in common. Antibiotic resistance became a risk in the 1950s, but a concerted global effort to manage it did not begin until after 2000. Widespread herbicide use began during the 1950s and was soon followed by an unabated rise in resistance. Here, we examine what lessons for combatting herbicide resistance could be learnt...
The translocation and assembly module (TAM) plays a role in the transport and insertion of proteins into the bacterial outer membrane. TamB, a component of this system spans the periplasmic space to engage with its partner protein TamA. Despite efforts to characterize the TAM, the structure and mechanism of action of TamB remained enigmatic. Here we present the crystal structure of TamB amino acids...
NagZ is an N‐acetyl‐β‐d‐glucosaminidase that participates in the peptidoglycan (PG) recycling pathway of Gram‐negative bacteria by removing N‐acetyl‐glucosamine (GlcNAc) from PG fragments that have been excised from the cell wall during growth. The 1,6‐anhydromuramoyl‐peptide products generated by NagZ activate β‐lactam resistance in many Gram‐negative bacteria by inducing the expression of AmpC β‐lactamase...
