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

P-glycoprotein (P-gp) can transport a wide variety of cytotoxic compounds that have diverse structures. Therefore, the drug-binding domain of the human multidrug resistance P-gp likely consists of residues from multiple transmembrane (TM) segments. In this study, we completed cysteine-scanning mutagenesis

Glutathione transferase P1-1 (GSTP1-1) plays crucial roles in cancer chemoprevention and chemoresistance and is a key target for anticancer drug development. Oxidative stress or inhibitor-induced GSTP1-1 oligomerization leads to the activation of stress cascades and apoptosis in various tumor cells.

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

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
