long interest in the physical aspects of membrane transport

processes—especially in phenomena related to charge transport—focuses now on

proton “pumps,” proton-coupled cation transporters, and potassium channels in

the plasma membranes of fungi, particularly Saccharomyces cerevisiae, Candida albicans (a pathogen), and Neurospora

crassa. Structure-function analysis of proteins

in these organisms is now possible, because of complete genome sequencing, and

the laboratory is using site-directed mutagenesis and heterologous expression

to analyze functional differences among analogous proteins in the three

species. Novel and surprising

properties have emerged, for example the development of enormous steady-state

membrane voltages (exceeding 350 mV), mediation of active potassium transport

by coupling to proton movements, and chloride channeling through potassium

transporters. Also, a major

current line of investigation is into the mechanisms by which small cationic

peptides (so-called RAMPs) produced by a wide variety of plant and animal

cells, become lethal to microorganisms, serving thereby as prototypes for new

classes of therapeutic drugs.
