The Escherichia coli protein SufI (FtsP) has recently been proposed to be a component of the cell division apparatus. The SufI protein is also in widespread experimental use as a model substrate in studies of the Tat (twin arginine translocation) protein transport system. We have used SufI-GFP (green fluorescent protein) fusions to show that SufI localizes to the septal ring in the dividing cel...

The function of SufI, a well-studied substrate of the TatABC translocase in Escherichia coli, is not known. It was earlier implicated in cell division, based on the finding that multiple copies of sufI suppressed the phenotypes of cells with mutations in ftsI (ftsI23), which encodes a divisomal transpeptidase. Recently, sufI was identified as both a multicopy suppressor gene and a synthetic let...

abstract: mystic literature (irfān) in general and sufi literature in particular has always been alluring to the scholars interestingly working in different fields from literary, religious, philosophical, historical to other fields which may have little in common. among sufi theologians, farid ud-din attar neishabouri is the one whom no one has ever been able to surpass in creating works which ...

a considerable part of persian classical literature is devoted to didactic literature. mysticism has also been very important in persian didactic literature and sufi tales are clear example of that; since all these tales have been used for the purpose of teaching. attar, one of the greatest persian poets, has paid lots of attention to these tales and has benefited them a lot in his works. attar...

The Tat system transports folded proteins across the bacterial cytoplasmic membrane and the thylakoid membrane of plant chloroplasts. In Escherichia coli substrate proteins initially bind to the integral membrane TatBC complex which then recruits the protein TatA to effect translocation. Overproduction of TatBC and the substrate protein SufI in the absence of TatA led to the accumulation of Tat...

The twin-arginine translocation (Tat) pathway in Escherichia coli transports fully folded and assembled proteins across the energy-transducing periplasmic membrane. In chloroplasts, Tat transport requires energy input only from the proton motive force. To elucidate the mechanism and energetics of bacterial Tat protein transport, we developed an efficient in vitro transport assay using TatABC-en...

The Tat (twin-arginine translocation) pathway is a Sec-independent mechanism for translocating folded preproteins across or into the inner membrane of Escherichia coli. To study Tat translocation, we sought an in vitro translocation assay using purified inner membrane vesicles and in vitro synthesized substrate protein. While membrane vesicles derived from wild-type cells translocate the Sec-de...

Dual-permeability models have been developed to account for the significant effects of macropore flow on contaminant transport, but their use is hampered by difficulties in estimating the additional parameters required. Therefore, our objective was to evaluate data requirements for parameter identification for predictive modeling with the dual-permeability model MACRO. Two different approaches ...
