Biophysical and physiological characterization of ZraP from Escherichia coli, the periplasmic accessory protein of the atypical ZraSR two-component system.
Petit-Härtlein I, Rome K, de Rosny E, Molton F, Duboc C, Gueguen E, Rodrigue A, Covès J. Petit-Härtlein I, et al. Among authors: rodrigue a. Biochem J. 2015 Dec 1;472(2):205-16. doi: 10.1042/BJ20150827. Epub 2015 Oct 5. Biochem J. 2015. PMID: 26438879
Similarly to CpxPAR, ZraPSR probably plays a role in envelope stress response as a zinc-dependent chaperone activity was demonstrated for ZraP in Salmonella. ...We propose an integrated mechanism in which zinc is a marker of envelope stress perturbation and Z …

Membrane targeting and translocation of bacterial hydrogenases.
Wu LF, Chanal A, Rodrigue A. Wu LF, et al. Among authors: rodrigue a. Arch Microbiol. 2000 May-Jun;173(5-6):319-24. doi: 10.1007/s002030000144. Arch Microbiol. 2000. PMID: 10896209 Review.
Periplasmic or membrane-bound bacterial hydrogenases are generally composed of a small subunit and a large subunit. The small subunit contains a peculiar N-terminal twin-arginine signal peptide, whereas the large subunit lacks any known targeting signal for e …

A decrease in total hydrogenase activity, together with accumulation of the precursors of the large subunits of HYD2 and HYD3, was also found to occur in a nickel uptake mutant (nik). ...In agreement with these in vivo results, we demonstrated a specific bind

Requirement for nickel of the transmembrane translocation of NiFe-hydrogenase 2 in Escherichia coli.
Rodrigue A, Boxer DH, Mandrand-Berthelot MA, Wu LF. Rodrigue A, et al. FEBS Lett. 1996 Aug 26;392(2):81-6. doi: 10.1016/0014-5793(96)00788-0. FEBS Lett. 1996. PMID: 8772179
Treatment of spheroplasts with trypsin was able to release active HYD2 into the soluble fraction, indicating that HYD2 is attached to the periplasmic side of the cytoplasmic membrane and that HYD2 undergoes a trans-membrane translocation during its biosynthesis. By using …
