introduction: acinetobacter baumannii is associated with hospital-acquired infections. outer membrane protein a of a.baumannii (abompa) is a well-characterized virulence factor which has important roles in pathogenesis of this bacterium. methods: based on our pcr-sequencing of ompa gene in the clinical isolates, abompa protein can be categorized into two types, named here type-1 and type-2. we ...

We present a new probabilistic model of evolution of RNA-, DNA-, or protein-like sequences and a tool rose that implements this model. By insertion, deletion and substitution of characters, a family of sequences is created from a common ancestor. During this artificial evolutionary process, the ’~true" history is logged and the "correct" multiple sequence alignment is ereated simultaneously. We...

The phylogenic and ontogenic expression of mRNA for the Na+/bile acid cotransporter was determined by Northern analysis utilizing a full-length cDNA probe recently cloned from rat liver. mRNA was detected in several mammalian species, including rat, mouse, and man, but could not be found in livers from nonmammalian species, including chicken, turtle, frog, and small skate. When expression of th...

Abstract Background Rose ( Rosa chinensis ) is a traditional famous flower with valuable ornamental characteristics. However, drought stress restricts its growth and development, leading to an abnormal phenotype. One of the main transcription factor (TF) protein groups in plant kingdom are APETALA2/ethylene-responsive (AP2/ERF) proteins potentially involved responses various plants. Results Our...

The paper discusses the importance of phylomemetic visualization to approach the cultural diversity in the social system like Indonesia, and thus revisit formal methodology regarding to the construction of the phylomemetic tree as an inspiration lent from the phylogenic analysis. A case of study is presented regarding to the data obtained from the diversity of traditionally inspired building-de...

During a survey in the year 2010, a novel phlebovirus was isolated from the Rousettus leschenaultii species of bats in western India. The virus was identified by electron microscopy from infected Vero E6 cells. Phylogenic analysis of the complete genome showed its close relation to severe fever with thrombocytopenia syndrome (SFTS) and Heartland viruses, which makes it imperative to further stu...

GPCR-GRAPA-LIB is a library of HMMs describing G protein coupled receptor families. These families are initially defined by class of receptor ligand, with divergent families divided into subfamilies using phylogenic analysis and knowledge of GPCR function. Protein sequences are applied to the models with the GRAPA curve-based selection criteria. RefSeq sequences for Homo sapiens, Drosophila mel...

serovar isolated from a canal in Louisiana in 1978 revealed it to be identical to that of V. cholerae 01 isolated in 1905 from a pilgrim at the El Tor quarantine station. The two strains are associated with sharply contrasting habitats. Ranges of variation of 5 to 15% in procaryotic 5S rRNA sequences between species are typical; variation within species may be 2% or greater. Because the 5S rRNA...

classify specified organisms taxonomically, determine the origins of proteinencoding genes, and infer how proteins function based on their conserved sequence motifs. Typically, phylogenic analysis involves two steps: constructing a phylogenetic tree or network based on the given biosequences and deriving biological information from the tree or network. Many computational methods have been devel...
