Genome sequencing and analysis of the versatile cell factory Aspergillus niger CBS 513.88
TLDR
The filamentous fungus Aspergillus niger is widely exploited by the fermentation industry for the production of enzymes and organic acids, particularly citric acid, and the sequenced genome revealed a large number of major facilitator superfamily transporters and fungal zinc binuclear cluster transcription factors. Expand
Properties and applications of starch-converting enzymes of the α-amylase family
Starch is a major storage product of many economically important crops such as wheat, rice, maize, tapioca, and potato. A large-scale starch processing industry has emerged in the last century. InExpand
A gene cluster encoding cholesterol catabolism in a soil actinomycete provides insight into Mycobacterium tuberculosis survival in macrophages
TLDR
The results suggest that cholesterol metabolism is central to M. tuberculosis's unusual ability to survive in macrophages and provide insights into potential targets for novel therapeutics. Expand
A novel class of secreted hydrophobic proteins is involved in aerial hyphae formation in Streptomyces coelicolor by forming amyloid-like fibrils.
TLDR
It is concluded that the amyloid-like fibrils of ChpD-H lower the water surface tension to allow aerial growth and cover aerial structures, rendering them hydrophobic. Expand
Glucansucrases: three-dimensional structures, reactions, mechanism, α-glucan analysis and their implications in biotechnology and food applications.
TLDR
An overview of glucansucrase enzymes, their recently elucidated crystal structures, their reaction and product specificity, and the structural analysis and applications of α-glucan polymers are provided. Expand
Structure-Function Relationships of Glucansucrase and Fructansucrase Enzymes from Lactic Acid Bacteria
TLDR
Emphasis now is on identification of residues and regions important for GS enzyme activity and product specificity (synthesis of α-glucans differing in glycosidic linkage type, degree and type of branching, glucan molecular mass, and solubility). Expand
The Actinobacterial mce4 Locus Encodes a Steroid Transporter*
TLDR
There is direct evidence that the Mce4 system of Rhodococcus jostii RHA1 is a steroid uptake system, and Bioinformatic analysis revealed that all mce4 loci in sequenced genomes are linked to steroid metabolism genes, predicting that all Mce 4 systems are steroid transporters. Expand
Nucleotide sequence and X-ray structure of cyclodextrin glycosyltransferase from Bacillus circulans strain 251 in a maltose-dependent crystal form.
The cyclodextrin glycosyltransferase (CGTase, EC 2.4.1.19) gene from Bacillus circulans strain 251 was cloned and sequenced. It was found to code for a mature protein of 686 amino acid residues,Expand
Production of actinorhodin-related "blue pigments" by Streptomyces coelicolor A3(2)
TLDR
Analysis of act mutants of S. coelicolor A3(2) confirmed that both pigments are derived from the act biosynthetic pathway, and synthesis of gamma-actinorhodin from actin orhodin is coupled to its export from the cell. Expand
Glucan synthesis in the genus Lactobacillus: isolation and characterization of glucansucrase genes, enzymes and glucan products from six different strains.
TLDR
For the first time, isolation and characterization of dextransucrase and mutansucrase genes and enzymes from various Lactobacillus species and the characterization of the glucan products synthesized are reported, which mainly have alpha-(1-->6)- and alpha-glucosidic linkages. Expand
