The signaling ligand (p)ppGpp regulates the enzyme HPRT across species by binding to a novel class of conserved motif, yet its specificity is allosterically altered through evolution of enzyme oligomerization.
Targeting the differentiation regulators and/or AMPs of keratinocytes, rather than targeting immune cells, may be an alternative approach for topical anti-psoriatic treatment, an area with high need for new drugs.
Tannic acid acts as an ‘antidote’ against the negative effects of a bacterial enzyme, which can both aggravate cystic fibrosis and enable the anthrax bacteria to evade the immune responses elicited by a typical live vaccine.
Imaging experiments and simulations reveal that the biophysical mechanism for force generation needed to engulf a forespore is based on coordinated cell wall synthesis and degradation.
Balanced peptidoglycan synthesis requires regulators, including sigma-I and WalKR, that coordinate the diffusive action of class A PBPs and the directional motion of the MreB-directed elongasome.
A multi-species chemical screening platform reveals a conserved role for p38 inhibition in modulating ryanodine receptor-related phenotypes and is adaptable to a range of neuromuscular disorders.
Synthetic single domain antibody libraries and a binder selection cascade encompassing ribosome and phage display enable the selection of conformation-specific binders against previously intractable membrane proteins within three weeks.
MERS-CoV infections in the Arabian Peninsula are the result of several hundred spillover events from viruses circulating in camels into the human population.
An ECF-type transporter serves as broad-spectrum heme iron scavenger and allows an opportunistic pathogen to use multiple eukaryotic hemoproteins to overcome nutritional iron-limitation.
