Ab initio synthesis by DNA polymerases
Ab initio DNA synthesis is a highly efficient DNA synthesis taking place in the absence of any added DNA. Incontrovertible evidence was obtained in the last decade.
Perspective
Clonal complexes of Staphylococcus aureus: all mixed and together
Staphylococcus aureus MLST scheme gathers the most important pathogenic clones in only one clonal complex by eBURST and a new approach is necessary to discriminate them.
Genome Announcement
Draft genomic DNA sequence of the facultatively methylotrophic bacterium Acidomonas methanolica type strain MB58
The unique ability of Acidomonas methanolica to grow on methanol medium might be due to acquisition of genes by horizontal gene transfer from phylogenetically diverse bacteria such as Actinobacteria.

Antifreeze protein activity in Arctic cryoconite bacteria
Cryoconite holes are a vital habitat for understanding the process of evolution and ecological behavior of microbes. Sequences of antifreeze proteins of Arctic Cryoconite bacteria belong to the family IBP-1, which is widely spread throughout the polar organisms.
Investigations on a hyper-proteolytic mutant of Beauveria bassiana: broad substrate specificity and high biotechnological potential of a serine protease
A hyper producing strain for protease production to degrade proteins in agro-food wastes, blood stains, or feathers among others.
Taxonomic revision of the cellulose-degrading fungus Acremonium cellulolyticus nomen nudum to Talaromyces based on phylogenetic analysis
We propose that the cellulose-degrading fungus Acremonium cellulolyticus nomen nudum is a new species, Talaromyces cellulolyticus, on the basis of morphology and molecular evidence.
Transcription factors spt3 and spt8 are associated with conidiation, mycelium growth, and pathogenicity in Fusarium graminearum
The SAGA complex components Fgspt3 and Fgspt8 are essential genes in Fusarium graminearum.
Genomic structure of bacteriophage 6H and its distribution as prophage in Flavobacterium psychrophilum strains
This study demonstrates world wide distribution of prophages in the fish pathogen Flavobacterium psychrophilum, which has implications for the application of phage therapy in aquaculture.
Oxygen distribution in proteins defines functional significance of the genome and proteome of the malaria parasite Plasmodium falciparum 3D7
Identification of proteins encoded by chromosome-9 (Chr-9) with outstanding oxygen (O-) content by determining the relative O-content of all of the proteins encoded by Chr-9 of Plasmodium falciparum 3D7.
GES-5 among the β-lactamases detected in ubiquitous bacteria isolated from aquatic environment samples
Azotobacter vinelandii siderophore can provide nitrogen to support the culture of the green algae Neochloris oleoabundans and Scenedesmus sp. BA032
Siderophores from the free-living diazotroph Azotobacter vinelandii are shown to support the growth of two green microalgae, Scenedesmus sp. BA032 and Neochloris oleoabundans as a source of nitrogen.
Plasmodium falciparum single-stranded DNA-binding protein (PfSSB) interacts with PfPrex helicase and modulates its activity
Plasmodium falciparum SSB interacts with PfPrex helicase and increases its helicase activity. Detailed domain mapping of PfSSB shows that N-terminal domain of PfSSB is involved in this interaction whereas C-terminal domain is regulating the PfPrex helicase activity.
Functional analysis of the N-terminal region of an essential histidine kinase, Hik2, in the cyanobacterium Synechocystis sp. PCC 6803
The authors constructed a fusion sensor to investigate a signal perception mechanism of histidine kinase in cyanobacterium, Synechocystis. They characterized an essential histidine kinase, Hik2, as a chloride ion sensor.
Role of sortase A in the pathogenesis of Staphylococcus aureus-induced mastitis in mice
The deficiency of sortase A affected the attachment of S. aureus to host cells. Thereby the activation of the NF-κB and MAPK signaling pathways were attenuated and decreased the susceptibility to mastitis.
Mutation of FVS1, encoding a protein with a sterile alpha motif domain, affects asexual reproduction in the fungal plant pathogen Fusarium oxysporum
This article reports that a novel protein with a sterile alpha motif is required for asexual reproduction in Fusarium oxysporum which produces three kinds of unique asexual spores.
