A comparison of DNA cleavage by the restriction enzymes SalPI and PstI [PDF]
Methods for obtaining highly active, exonuclease-free, stable preparations of the Streptomyces albus P restriction enzyme SalPI are described. SalPI and its isoschizomer PstI (from the taxonomically distant Providencia stuartii 164) both cleave their recognition sequence (5'-CTGCAG-3') to generate fragments terminating in tetranucleotide 3' extensions ...

PCR-RFLP of mitochondrial DNA of swamp buffaloes in breeding station
Methods have been devised for detecting polymorphisms in the D-loop regions using the PCR followed by restriction enzyme digestion to reveal restriction fragment length polymorphism.

Whole genome phylogeny for 21 Drosophila species using predicted 2b-RAD fragments [PDF]
Type IIB restriction endonucleases are site-specific endonucleases that cut both strands of double-stranded DNA upstream and downstream of their recognition sequences.

Mechanism of DNA Recognition by the Restriction Enzyme EcoRV
EcoRV, a restriction enzyme in Escherichia coli, destroys invading foreign DNA by cleaving it at the center step of a GATATC sequence. In the EcoRV-cognate DNA crystallographic complex, a sharp kink of 50 degrees has been found at the center base-pair step (TA).

The average spacing of restriction enzyme recognition sites in DNA [PDF]
The discovery of naturally occurring enzymes which cleave DNA at sites specific to particular nucleotide sequences has had a great impact on molecular biology. The function of these enzymes in uivo is to protect bacterial cells from viral invasion by degradation of foreign DNA.

Reciprocal control of viral infection and phosphoinositide dynamics
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

On the DNA cleavage mechanism of Type I restriction enzymes [PDF]
Although the DNA cleavage mechanism of Type I restriction-modification enzymes has been extensively studied, the mode of cleavage remains elusive. In this work, DNA ends produced by EcoKI, EcoAI and EcoR124I, members of the Type IA, IB and IC families, respectively, have been characterized by cloning and sequencing restriction products from the ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.
