Automata for DNA splicing languages with two restriction enzymes
DNA splicing system is modelled by the process of recombinant DNA that generates a language which is known as a splicing language. In DNA splicing system, molecules are cut and recombined with the existence of restriction enzymes and a ligase to produce

PCNA stimulates catalysis by structure-specific nucleases using two distinct mechanisms : substrate targeting and catalytic step [PDF]
This work was supported by the Biotechnology and Biological Sciences Research Council [grants BBD0014391 and BBE0146741]The sliding clamp Proliferating Cell Nuclear Antigen (PCNA) functions as a recruiter and organizer of a wide variety of DNA modifying ...

Rapid identification and differentiation of the vaccine strain Rac H from EHV 1 field isolates using a non-radioactive DNA probe [PDF]
A method for rapid differentiation between the EHV 1 live vaccine strain Rac H and field isolates is described. Total DNA was isolated from virus-infected small scale cell cultures.

How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

MITOCHONDRIAL DNA POLYMORPHISMS AND FERTILITY IN BEEF CATTLE [PDF]
Two regions of mitochondrial DNA, D-loop and ND-5 were characterized using polymerase chain reaction – restriction fragment length polymorphism (PCR-RFLP) involving 422 beef cattle of Hereford and composite breeds from Wokalup’s ...

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

DNA Cloning without Restriction Enzyme and Ligase
One common problem in using the traditional DNA cloning procedure is that suitable natural restriction sites are often unavailable for a given task. Creating new restriction sites is often time consuming. Here, I describe a simple technique of producing "customized cohesive ends" by a combination of PCR primer design and lambda exonuclease digestion ...

Investigation of DNA-protein Sequence-Specific Interactions with a ds-DNA Array
The sequence specific recognitions between DNAs and proteins play important roles in many biological functions. The use of double-stranded DNA arrays (ds-DNA arrays) for studying sequence specific recognition between DNAs and proteins is a promising ...

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.

The ubiquitin system in normal and infected germinal center B cells
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 ...
