The white, brown and scarlet genes of Drosophila melanogaster encode proteins which
transport guanine or tryptophan (precursors of the red and brown eye colour pigments) and …

Background: Proton-translocating ATP synthases convert the energy generated from
photosynthesis or respiration into ATP. These enzymes, termed F 0 F 1 -ATPases, are structurally …

The white, brown, and scarlet genes of Drosophila melanogaster encode three proteins that
belong to the Traffic ATPase superfamily of transmembrane permeases and are involved in …

Escherichia coli contains two major systems for transporting inorganic phosphate (P i ). The
low-affinity P i transporter (pitA) is expressed constitutively and is dependent on the proton …

The white, scarlet, and browngenes of Drosophila melanogasterencode ABC transporters
involved with the uptake and storage of metabolic precursors to the red and brown eye colour …

The Vpu protein of human immunodeficiency virus type 1 forms cation-selective ion channels
and enhances the process of virion budding and release. Mutagenesis studies have …

At least four genes are known to affect formation of the cytochrome bd‐type terminal oxidase
of Escherichia coli. In addition to the genes (cydA and cydB) encoding the two constituent …

… A model for the mechanism of ATP synthase was proposed previously (Cox, GB, Jans, DA, …
To test this proposal the Lys-23 of the b subunit was replaced by threonine using site-directed …

The substitution of arginine at position 210 in the a subunit of Escherichia coli F 0 F 1 -ATPase
by either lysine or alanine causes dominance in complementation tests with a …

The Escherichia coli Pst system is a periplasmic phosphate permease. A mutational analysis
of the requirement for function of specific charged residues or proline residues in the two …
