New E. coli Cloning Vector Using a Cellulase Gene (celA) as a Screening Marker

open access: yesBioTechniques, 2001
The extracellular endoglucanase A gene of Clostridium thermocellum (celA) was used as a screening marker for E. coli cloning vector. A 1.4-kb EcoRI fragment containing celA from pTvec/celA was isolated and cloned into a pUC18 deleting β-galactosidase ...

Structural and biochemical analysis of a B12 superbinder

open access: yesFEBS Letters, EarlyView.
BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Resistance and susceptibility to late blight in Solanum: gene mapping, cloning and stacking [PDF]

open access: yes, 2010
The potato late blight disease, caused by the oomycete Phytophthora infestans, is a major threat for potato production worldwide. To breed potato varieties with durable resistance against P. infestans, it is necessary to combine two or more resistance (R)

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

open access: yesFEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

open access: yesFEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

Gene Cloning and DNA Analysis: An Introduction, 5th ed [PDF]

open access: yes, 2006
Book Review: Terence A. Brown. Blackwell Publishing, Oxford. 2006. 386 pp. $69.95. The textbook that became almost a classic in the field of molecular genetics and gene cloning deserved to be revised and published in this fifth edition.

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

open access: yesFEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

A novel Gateway®-compatible binary vector allows direct selection of recombinant clones in Agrobacterium tumefaciens

open access: yesPlant Methods, 2011
Background Cloning genes into plasmid vectors is one of the key steps for studying gene function. Recently, Invitrogen™ developed a convenient Gateway® cloning system based on the site-specific DNA recombination properties of bacteriophage lambda and the

The ubiquitin system in normal and infected germinal center B cells

open access: yesFEBS Letters, EarlyView.
The ubiquitin system plays a central role in germinal center (GC) B cells, influencing differentiation to long‐lived memory B cells. Oncogenic gammaherpesviruses gain access to memory B cells by establishing latency in GC B cells. Mapping ubiquitin mechanisms in normal and infected GC B cells will define specific molecular circuits in B cells germane ...

The Carcinoembryonic Antigen Gene Family [PDF]

open access: yes, 1988
The molecular cloning of carcinoembryonic antigen (CEA) and several cross-reacting antigens reveals a basic domain structure for the whole family, which shows structural similarities to the immunoglobulin superfamily.
