Stimulation of the ATPase activity of the yeast mitochondrial ABC transporter Atm1p by thiol compounds.

abstract：:PagP is a bacterial outer membrane protein consisting of an 8 stranded transmembrane beta-barrel and an N-terminal alpha-helix. It is an enzyme which catalyses transfer of a palmitoyl chain from a phospholipid to lipid A. Molecular dynamics simulations have been used to compare the dynamic behaviour in simulations sta...
