Seasonal Expression of the Picocyanobacterial Phosphonate Transporter Gene phnD in the Sargasso Sea
In phosphorus-limited marine environments, picocyanobacteria (Synechococcus and Prochlorococcus spp.) can hydrolyze naturally occurring phosphonates as a P source. Utilization of 2-aminoethylphosphonate (2-AEP) is dependent on expression of the phn genes, encoding functions required for uptake, and C-P bond cleavage. Prior work has indicated that expression of picocyanobacterial phnD, encoding ...
متن کاملThe inhibition of phosphatidylglycerol synthesis in Escherichia coli by 3,4-dihydroxybutyl-1-phosphonate.
The effect of 3,4-dihydroxybutyl-1-phosphonate on phosphoglyceride metabolism of Escherichia coli strain 8 was examined. The compound inhibits the incorporation of [33P]phosphate into phospholipids. Phosphatidylglycerol accumulation is very strongly inhibited, while phosphatidylethanolamine and cardiolipin accumulation are less significantly affected. Pulse labeling studies using [32P]phosphate...
متن کاملPhosphonate utilization by bacteria.
Bacteria able to use at least one of 13 ionic alkylphosphonates of O-alkyl or O,O-dialkyl alkylphosphonates as phosphorus sources were isolated from sewage and soil. Four of these isolates used 2-aminoethylphosphonic acid (AEP) as a sole carbon, nitrogen, and phosphorus source. None of the other phosphonates served as a carbon source for the organisms. One isolate, identified as Pseudomonas put...

هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...
15 صفحه اولStructure of the Escherichia coli ProQ RNA-binding protein.
The protein ProQ has recently been identified as a global small noncoding RNA-binding protein in Salmonella, and a similar role is anticipated for its numerous homologs in divergent bacterial species. We report the solution structure of Escherichia coli ProQ, revealing an N-terminal FinO-like domain, a C-terminal domain that unexpectedly has a Tudor domain fold commonly found in eukaryotes, and...
