Analysis of SecA Dimerization in Solution
The Sec pathway mediates translocation of protein across the inner membrane of bacteria. SecA is a motor protein that drives translocation of preprotein through the SecYEG channel. SecA reversibly dimerizes under physiological conditions, but different dimer interfaces have been observed in SecA crystal structures. Here, we have used biophysical approaches to address the nature of the SecA dime...
متن کاملBinding of SecA to the SecYEG complex accelerates the rate of nucleotide exchange on SecA.
SecYEG translocase mediates the transport of preproteins across the inner membrane of Escherichia coli. SecA binds the membrane-embedded SecYEG protein-conducting channel with high affinity and then drives the stepwise translocation of preproteins across the membrane through multiple cycles of ATP binding and hydrolysis. We have investigated the kinetics of nucleotide binding to SecA while asso...

0022-2836/$ see front matter © 2008 E Gadd45α, β, and γ proteins, also known as growth arrest and DNA damage-inducible factors, have a number of cellular functions, including cell-cycle regulation and propagation of signals produced by a variety of cellular stimuli, maintaining genomic stability and apoptosis. Furthermore, Gadd45β has been indicated as a major player in the endogenous NF-κBmedi...
متن کاملAdsorption Behavior of MWAR Toward Gd(III) in Aqueous Solution
Adsorption and desorption behavior of Gd(III) ionon macroporous weak acid resin (MWAR) had been investigated.The influence of operational conditions such as contact time, initial concentration of Gd(III) ion, initial pH of solution and temperature on the adsorption of Gd(III) ion had been examined. Experimental data were exploited for kinetic and thermodynamic evaluations ...
