Galactose Metabolism Plays a Crucial Role in Biofilm Formation by Bacillus subtilis [PDF]

open access: yes, 2014
Galactose is a common monosaccharide that can be utilized by all living organisms via the activities of three main enzymes that make up the Leloir pathway: GalK, GalT, and GalE.

An ABC transporter containing a forkhead-associated domain interacts with a serine-threonine protein kinase and is required for growth of Mycobacterium tuberculosis in mice [PDF]

open access: yes, 2005
Forkhead-associated (FHA) domains are modular phosphopeptide recognition motifs with a striking preference for phosphothreonine-containing epitopes. FHA domains have been best characterized in eukaryotic signaling pathways but have been identified in six

The incoherent feed‐forward loop can generate non‐monotonic input functions for genes

open access: yesMolecular Systems Biology, 2008
Gene regulation networks contain recurring circuit patterns called network motifs. One of the most common network motif is the incoherent type 1 feed‐forward loop (I1‐FFL), in which an activator controls both gene and repressor of that gene.

Unraveling the molecular basis of subunit specificity in P pilus assembly by mass spectrometry [PDF]

open access: yes, 2008
P pili are multisubunit fibers essential for the attachment of uropathogenic Escherichia coli to the kidney. These fibers are formed by the noncovalent assembly of six different homologous subunit types in an array that is strictly defined in terms of ...

Analysis of Benzoate 1,2‐Dioxygenase Identifies Shared Electron Transfer Components With DxnA1A2 in Rhizorhabdus wittichii RW1

open access: yesJournal of Basic Microbiology, EarlyView.
ABSTRACT Rhizorhabdus wittichii RW1 is known for its ability to degrade polycyclic aromatic hydrocarbons, such as dibenzo‐p‐dioxin (DD) and dibenzofuran (DF). We hypothesized that the R. wittichii RW1 benzoate 1,2‐dioxygenase shares electron transfer components with the DD/DF angular dioxygenase (DxnA1A2), similar to many aromatic hydrocarbon degrading

Transcriptional control of the H-NS antagonists LeuO and RcsB-BglJ in Escherichia coli [PDF]

open access: yes, 2012
The bacterial nucleoid-associated protein (NAP) H-NS is involved in the organization and compaction of the bacterial chromatin and acts as a global respressor, mainly of genes that have been acquired by horizontal gene transfer and that are related to ...

Revision and expansion of the genus Spirirestis (Tolypothrichaceae, Cyanobacteria)

open access: yesJournal of Phycology, EarlyView.
Abstract Recent phylogenetic analyses of members of the Tolypothrichaceae (Nostocales, Cyanobacteria) based on 16S rRNA gene sequence data have demonstrated that the soil‐inhabiting members of the family belong to a clade separate from the aquatic and subaerial members of the family.

Biological Consequences of Tightly Bent DNA: The Other Life of a Macromolecular Celebrity [PDF]

open access: yes, 2006
The mechanical properties of DNA play a critical role in many biological functions. For example, DNA packing in viruses involves confining the viral genome in a volume (the viral capsid) with dimensions that are comparable to the DNA persistence length ...

Staphylococcus aureus COL: An Atypical Model Strain of MRSA That Exhibits Slow Growth and Antibiotic Tolerance due to a Mutation in PRPP Synthetase

open access: yesMolecular Microbiology, EarlyView.
COL is an unusual “model” strain of Staphylococcus aureus that exhibits slow growth and multidrug antibiotic tolerance. This phenotype is primarily due to a mutation in Prs, which synthesizes the core metabolite phosphoribosyl pyrophosphate (PRPP). Introduction of the COL Prs allele into the antibiotic‐susceptible strain Newman confers tolerance, while

DASH: a versatile and high‐capacity gene stacking system for plant synthetic biology

open access: yesPlant Biotechnology Journal, EarlyView.
Summary DNA assembly systems based on the Golden Gate method are popular in synthetic biology but have several limitations: small insert size, incompatibility with other cloning platforms, DNA domestication requirement, generation of fusion scars, and lack of post‐assembly modification.
