TF (tissue factor) is a transmembrane cofactor that initiates blood coagulation in mammals by binding Factor VIIa to activate Factors X and IX. The cofactor can reside in a cryptic configuration on primary cells and de-encryption may involve a redox

We identified a thiol-reactive compound, dibromobimane (dBBn), that was a potent stimulator (8.2-fold) of the ATPase activity of Cys-less P-glycoprotein. We then used this compound together with cysteine-scanning mutagenesis to identify residues in transmembrane segment (TM) 6 and TM12 that

Membrane-intrinsic enzymes are embedded in lipids, yet how such enzymes interrogate lipid substrates remains a largely unexplored fundamental question. The outer membrane phospholipid:lipid A palmitoyltransferase PagP combats host immune defenses during infection and selects a palmitate chain using its beta-barrel

The structure of the pore is critical to understanding the molecular mechanisms underlying selective permeation and voltage-dependent gating of channels formed by the connexin gene family. Here, we describe a portion of the pore structure of unapposed hemichannels formed by

The ArsA ATPase is the catalytic subunit of the ArsAB pump encoded by the arsRDABC operon of Escherichia coli plasmid R773. ArsD is a metallochaperone that delivers As(III) to ArsA, increasing its affinity for As(III), thus conferring resistance to environmental
