Half-molecule ATP-binding cassette transporters of the HMT-1 (heavy metal tolerance factor 1) subfamily are required for Cd2+ tolerance in Schizosaccharomyces pombe, Caenorhabditis elegans, and Chlamydomonas reinhardtii. Based on studies of S. pombe, it has been proposed that SpHMT-1 transports heavy metal.phytochelatin (PC) complexes into the ...

Half molecule ATP-binding cassette transporters of the HMT1(heavy metal tolerance factor 1)subfamily are required for Cd2+ tolerance in Schizosaccharomyces pombe, Caenorhabditis elegans and Chlamydomonas reinhardtii, and have homologs in other species, including plants and humans. Based on studies i...

BackgroundMembers of the HMT-1 (heavy metal tolerance factor 1) subfamily of the ATP-binding cassette (ABC) transporter superfamily detoxify heavy metals and have unique topology: they are half-molecule ABC transporters that, in addition to a single transmembrane domain (TMD1) and a single nucleotide-binding domain ...

BackgroundDeveloping methods for protecting organisms in metal-polluted environments is contingent upon our understanding of cellular detoxification mechanisms. In this regard, half-molecule ATP-binding cassette (ABC) transporters of the HMT-1 subfamily are required for cadmium (Cd) detoxification. HMTs have conserved structural architecture that ...
Hmt1 is the major type I arginine methyltransferase in the yeast Saccharomyces cerevisiae and facilitates the nucleocytoplasmic transport of mRNA-binding proteins through their methylation. Here we demonstrate that Hmt1 is recruited during the beginning of the transcriptional elongation process. ...

-binding proteins (SBPs) of ATP Binding Cassette (ABC) transporters has been ongoing for at least four decades. Our on the lactococcal oligopeptide binding protein A (OppA), the receptor component of the ABC-transporter oligopeptide picture how these proteins work. Three types of ABC-transporters exist: ...

Etravirine is a novel nonnucleoside reverse transcriptase inhibitor (NNRTI) for the treatment of HIV-1 infections. ABC transporters potentially mediate clinically relevant drug-drug interactions. We assessed substrate characteristics and the inhibitory and inductive potential of etravirine on ABC transporters. ...
FIGURE 1. The minimal ABC transporter has four domains. Two transmembrane domains (TMDs) bind ligand, and transport is driven by ATP binding and hydrolysis by the two nucleotide binding domains (NBDs). The TMDs from different subfamilies of ABC transporters are not necessarily homologous. The ...
