Genome level information coupled with phylogenetic analysis of specific genes and gene families allow for a better understanding of the structure and function of their protein products. In this study, we examine the mammalian uroplakins (UPs) Ia and Ib, members of the tetraspanin superfamily, that interact with uroplakins UPII and UPIIIa/IIIb, respectively,(More)
Eubacterial genomes have highly variable GC content (0.17-0.75) and the primary mechanism of such variability remains unknown. The place to look for is what actually catalyzes the synthesis of DNA, where DNA polymerase III is at the center stage, particularly one of its 10 subunits--the alpha subunit. According to the dimeric combination of alpha subunits,(More)
Among prokaryotic genomes, the distribution of genes on the leading and lagging strands of the replication fork is known to be biased. Several hypotheses explaining this strand-biased gene distribution (SGD) have been proposed, but none have been tested or supported by sufficient data analyses. In this work we have analyzed 211 prokaryotic genomes in terms(More)
Nucleotide compositional analyses of disparities in genomic guanine and cytosine (gGC) content directly relate to the amino acid composition, through the union of the genetic code. Here we analyzed 229 prokaryotic genomes to address the intricate relationships between gGC, amino acids and their codons in the context of genes. First, we not only confirmed(More)
We studied structural and immunological properties of the SARS-CoV M (membrane) protein, based on comparative analyses of sequence features, phylogenetic investigation, and experimental results. The M protein is predicted to contain a triple-spanning transmembrane (TM) region, a single N-glycosylation site near its N-terminus that is in the exterior of the(More)
The Coronaviridae family is characterized by a nucleocapsid that is composed of the genome RNA molecule in combination with the nucleoprotein (N protein) within a virion. The most striking physiochemical feature of the N protein of SARS-CoV is that it is a typical basic protein with a high predicted pI and high hydrophilicity, which is consistent with its(More)
Up to now, the literature on Cu2S with specific morphology applied to oxygen evolution reaction (OER) in the electrocatalytic field has been limited. In this work, unique peapod-like Cu2S/C exhibiting superb electrocatalytic performance toward OER is successfully synthesized, by employing Cu(OH)2 nanorods as the template and nontoxic glucose as the carbon(More)
With the growing population and the reducing arable land, breeding has been considered as an effective way to solve the food crisis. As an important part in breeding, high-throughput phenotyping can accelerate the breeding process effectively. Light detection and ranging (LiDAR) is an active remote sensing technology that is capable of acquiring(More)
As a large carbon pool, global forest ecosystems are a critical component of the global carbon cycle. Accurate estimations of global forest aboveground biomass (AGB) can improve the understanding of global carbon dynamics and help to quantify anthropogenic carbon emissions. Light detection and ranging (LiDAR) techniques have been proven that can accurately(More)
In order to develop clinical diagnostic tools for rapid detection of the SARS-CoV (severe acute respiratory syndrome-associated coronavirus) and to identify candidate proteins for vaccine development, the C-terminal portion of the nucleocapsid (NC) gene was amplified using RT-PCR from the SARS-CoV genome, cloned into a yeast expression vector (pEGH), and(More)
