The role of charges near the pore mouth has been discussed in theoretical work about ion channels. To introduce new negative charges in a channel protein, amino groups of porin from Rhodobacter capsulatus 37b4 were succinylated with succinic anhydride, and the precise extent and sites of succinylations and structures of the succinylporins determined by mass spectrometry and X-ray crystallograph...

Title of Thesis: Investigation of the Basis for Persistent Porin Serotypes of Neisseria gonorrhoeae in Community Infections Lotisha Erin Garvin, Master Degree, 2006 Thesis directed by: Ann Jerse, Ph. D. Associate Professor, Department of Microbiology and Immunology Uniformed Services University Neisseria gonorrhoeae porin (por), a major outer membrane protein, has been studied extensively in va...

Mitochondrial outer membrane permeability is conferred by a family of porin proteins. Mitochondrial porins conduct small molecules and constitute one component of the permeability transition pore that opens in response to apoptotic signals. Because mitochondrial porins have significant roles in diverse cellular processes including regulation of mitochondrial ATP and calcium flux, we sought to d...

cDNA encoding porin of Neurospora crassa, the major protein component of the outer mitochondrial membrane, was isolated and the nucleotide sequence was determined. The deduced protein sequence consists of 283 amino acids (29,979 daltons) and shows sequence homology of around 43% to yeast porin; however, no significant homology to bacterial porins was apparent. According to secondary structure p...

The plasmid-encoded pco copper resistance operon in Escherichia coli consists of seven genes that are expressed from two pco promoters in response to elevated copper; however, little is known about how they mediate resistance to excess environmental copper. Two of the genes encode the soluble periplasmic proteins PcoA and PcoC. We show here that inactivation of PcoC, and PcoA to a lesser extent...

The title complex, [CoNa(CO5P)(H2O)5]n, was obtained by reacting sodium phosphono-formate with cobalt nitrate. The complex contains cobalt(II) and sodium ions, which are bridged by the O atoms of two aqua ligands. The Co(II) ion is octahedrally coordinated by three phosphonoformato ligands (one bi- and the other monodentate) and by two O atoms from the bridging aqua ligands. The sodium cation i...

Taking northern Xinjiang, China, as an example, this study first compares the standard MODIS Terra and Aqua snow cover classifications, and then compares the accuracy of the standard MODIS daily and 8-day snow cover products with the new daily and multi-day snow cover combination of MODIS Terra and Aqua observations using in situ measurements. Under clear sky in both products, the agreement of ...

We previously reported increased running economy and joint range of motion (ROM) during subsequent exercise performed 48-h following strenuous exercise while wearing garments containing micro-titanium particles generated from high-pressure aqueous processing of titanium (AQUA TITAN(TM)). Here we utilised an isolated plantarflexion triceps surae model and AQUA TITAN-treated flexible tape to dete...

Article history: Received 15 July 2009 Received in revised form 8 February 2010 Accepted 9 April 2010 The latestMODIS aerosol optical depth (AOD) retrieval algorithm (C005) based on analyses of global AERONET data for both Terra and Aqua satellites has gradually supplanted the older algorithm (C004) since 2006. However, due to few AERONET sites in China, assessing applications of MODIS products...
