Genome Sequence of the Streptomycin-Producing Microorganism Streptomyces griseus IFO 13350
ABSTRACT We determined the complete genome sequence of Streptomyces griseus IFO 13350, a soil bacterium producing an antituberculosis agent, streptomycin, which is the first aminoglycoside
An isoflavone conjugate-hydrolyzing beta-glucosidase from the roots of soybean (Glycine max) seedlings: purification, gene cloning, phylogenetics, and cellular localization.
TLDR
The purification and cDNA cloning of this important beta-glucosidase from the roots of G. max seedlings as well as related phylogenetic and cellular localization studies revealed that the enzyme is exclusively localized in the cell wall and intercellular space of seedling roots.
Structural and Mutational Studies of Anthocyanin Malonyltransferases Establish the Features of BAHD Enzyme Catalysis*
TLDR
The structure and results of mutational analyses allowed us to identify the acyl-acceptor binding site of anthocyanin malonyltransferases, which is structurally different from the corresponding portion of vinorine synthase, another BAHD member, thus permitting the diversity of the acel- acceptor specificity of BAHD family to be understood.
Proposed mechanism and functional amino acid residues of malonyl-CoA:anthocyanin 5-O-glucoside-6'''-O-malonyltransferase from flowers of Salvia splendens, a member of the versatile plant
TLDR
A general base deprotonates the 6' "-hydroxyl group of the anthocyanin substrate, thereby promoting a nucleophilic attack on the carbonyl of the thioester of malonyl-CoA; His167 and Asp390 appear to be involved in the general acid/base mechanism of Ss5MaT1.
cDNA Cloning, Heterologous Expressions, and Functional Characterization of Malonyl-Coenzyme A:Anthocyanidin 3-O-Glucoside-6"-O-Malonyltransferase from Dahlia Flowers1
TLDR
It is suggested that malonylation should serve as a strategy for pigment stabilization in the flowers as well as the other enzymatic profiles of the recombinant Dv3MaT were closely related to those of native anthocyanin malonyltransferase activity in the extracts of dahlia flowers.
Genetic transformation of Geobacillus kaustophilus HTA426 by conjugative transfer of host-mimicking plasmids.
TLDR
The results demonstrate that conjugative transfer is a promising approach for introducing exogenous DNA into thermophiles and increases the potential of G. kaustophilus HTA426 as a thermophilic host to be used in various applications and as a model for biological studies of this genus.
Polysaccharide-Degrading Thermophiles Generated by Heterologous Gene Expression in Geobacillus kaustophilus HTA426
TLDR
A new inducible gene expression system in the thermophile Geobacillus kaustophilus HTA426 is described, generating thermophiles with the potential to degrade plant biomass and cellulase and α-amylase genes conferred the ability to degrade cellulose paper and insoluble starch at high temperatures.
Three inositol dehydrogenases involved in utilization and interconversion of inositol stereoisomers in a thermophile, Geobacillus kaustophilus HTA426.
TLDR
Analysis of metabolites in HTA426 cells grown in the presence of MI revealed that substantial amounts of DCI and SI appeared intracellularly during the stationary phase, while only MI was present in PS8 cells, suggesting that interconversion of inositol stereoisomers may involve these three enzymes.
UDP-glucuronic Acid:Anthocyanin Glucuronosyltransferase from Red Daisy (Bellis perennis) Flowers
In contrast to the wealth of biochemical and genetic information on vertebrate glucuronosyltransferases (UGATs), only limited information is available on the role and phylogenetics of plant UGATs.
