Performance of STAR-Light receivers during CLPX

IGARSS 2003. 2003 IEEE International Geoscience and Remote Sensing Symposium. Proceedings (IEEE Cat. No.03CH37477), 2004
STAR-Light is a 10 element, 1.4 GHz aperture synthesis radiometer being developed at the University of Michigan. It features 3 new technologies: 1) 2-dimensional aperture synthesis using 3-bit correlation, 2) Direct Sampling Digital Receiver (DSDR) architecture, and 3) band definition in the digital definition in the digital domain.

Maintenance of mitochondrial genome distribution by mitochondrial AAA+ protein ClpX

Experimental Cell Research, 2012
The segregation of mitochondrial DNA (mtDNA) is important for the maintenance and transmission of the genome between generations. Recently, we clarified that human mitochondrial transcription factor A (TFAM) is required for equal distribution and symmetric segregation of mtDNA in cultured cells; however, the molecular mechanism involved is largely ...

Comparison with CLPX II airborne data using DMRT model

2009 IEEE International Geoscience and Remote Sensing Symposium, 2009
In this paper, we considered a physical-based model which use numerical solution of Maxwell Equations in three-dimensional simulations and apply into Dense Media Radiative Theory (DMRT). The model is validated in two specific dataset from the second Cold Land Processes Experiment (CLPX II) at Alaska and Colorado. The data were all obtain by the Ku-band

Global Inventory of ClpP- and ClpX-Regulated Proteins in Staphylococcus aureus

Journal of Proteome Research, 2020
Staphylococcus aureus represents an opportunistic pathogen, which utilizes elaborate quorum sensing mechanisms to precisely control the expression and secretion of virulence factors. Previous studies indicated a role of the ClpXP proteolytic system in controlling pathogenesis. While detailed transcriptome data for S.

The Impact of Snow Model Complexity at Three CLPX Sites

Journal of Hydrometeorology, 2008
Abstract Many studies have developed snow process understanding by exploring the impact of snow model complexity on simulation performance. This paper revisits this topic using several recently developed land surface models, including the Simplified Simple Biosphere Model (SSiB); Noah; Variable Infiltration Capacity (VIC); Community Land

The ClpX heat-shock protein of Escherichia coli, the ATP-dependent substrate specificity component of the ClpP-ClpX protease, is a novel molecular chaperone

EMBO Journal, 1995
All major classes of protein chaperones, including DnaK (the Hsp70 eukaryotic equivalent) and GroEL (the Hsp60 eukaryotic equivalent) have been found in Escherichia coli. Molecular chaperones enhance the yields of correctly folded polypeptides by preventing aggregation and even by disaggregating certain protein aggregates. Previously, we identified the

Regulation of Erythroid Heme Synthesis By the Mitochondrial Clpx Unfoldase

Blood, 2019
Differentiating erythroid cells synthesize large quantities of heme for hemoglobinization. While the transcriptional regulation and enzymatic mechanisms of the heme synthetic enzymes are well characterized, we lack mechanistic understanding of how their protein stability, cofactor incorporation and functional interactions with mitochondrial ...

[Bacterial ClpX protease structure and function--a review].

Wei sheng wu xue bao = Acta microbiologica Sinica, 2011
ClpX is a member of Hsp100 (heat-shock protein) family which is conserved among organisms. Hsp100/ Clp implicates in stress resistance, intracellular protein turn-over, DNA replication and regulation of gene expression. Tuberculosis remains one of the major threats to human health.

Funkce šaperonu ClpX u bakterií

2020
Intracellular proteolysis is an essential regulatory process that affects cellular physiology. Since proteolysis destroys proteins irreversibly, this process must be strictly controlled. The AAA+ proteins are the key factors in regulated proteolysis in bacteria.

CLPX and CLPP proteins are required for regulation of ALAS2

2021
Heme synthesis consists of a series of eight enzymatic steps that result in the synthesis of porphyrin products, which in turn can be used to generate other tetrapyrrole compounds. In late-stage erythropoiesis, these precursors can be converted into its terminal product, heme.
